Pressure on members of the electoral college to select someone other than Donald Trump has grown dramatically — and noisily — in recent weeks, causing some to waver but yielding little evidence that Trump will fall short when electors convene in most state capitals Monday to cast their votes.

Carole Joyce of Arizona expected her role as a GOP elector to be pretty simple: She would meet the others in Phoenix and carry out a vote for Trump, who won the most votes in her state and whom she personally supported.

But then came the mail and the emails and the phone calls — first hundreds, then thousands of voters worrying that Trump’s impulsive nature would lead the country into another war.

“Honestly, it had an impact,” said Joyce, a 72-year-old Republican state committee member. “I’ve seen enough funerals. I’m tired of hearing bagpipes. . . . But I signed a loyalty pledge. And that matters.”

Such is the life these days for many of the 538 men and women who are scheduled to meet Monday across the country to carry out what has traditionally been a perfunctory vote after most every presidential election.

The role of elector has intensified this year, in the wake of a bitter election in which Trump lost the popular vote to Democrat Hillary Clinton by a margin of nearly 3 million votes and the revelation of a secret CIA assessment that Russia interfered to help Trump get elected.

Amid the uncertainty caused by Russian influence, 10 electors — nine Democrats and one Republican — asked for an intelligence briefing to get more information about Moscow’s role. Their request was endorsed by John Podesta, Clinton’s campaign manager.

“The administration should brief members of the electoral college on the extent and manner of Russia’s interference in our election before they vote on Dec. 19,” Podesta wrote Thursday in aWashington Post op-ed.

The Office of the Director of National Intelligence said Friday evening that it would not brief the electors, because it is engaged in a presidentially ordered review of the Russian interference. “Once the review is complete in the coming weeks, the intelligence community stands ready to brief Congress” and may release findings, the ODNI said in a statement posted to its website.

Meanwhile, Joyce and the other 305 Republican electors who are supposed to cast their votes for Trump have been subject to intense campaigns orchestrated by anti-Trump forces to convince them that they alone can block the reality-television star from the White House.

Others have targeted Democratic electors, who are supposed to cast votes for Clinton, to persuade them to switch to a more conventional Republican who could also draw enough support from GOP electors to swoop into office.

While there is little sign the efforts will prove successful, the push has unleashed intense pressure on individual electors, who have now been thrust into a sometimes uncomfortable spotlight.

Joyce has received emails from “Benjamin Franklin” and “John Jay” — and a Christmas card that read: “Please, in the name of God, don’t vote for Trump.”

The rancor about the role of electors started early in the campaign. In August, Baoky Vu, a GOP activist in Atlanta, said he planned to resign from the job because he was so morally opposed to Trump. He planned to defer his voting responsibility to someone more willing — an alternate who would be put in place Monday.

After the election, Vu started getting phone calls and emails asking him not to resign. He was asked instead to consider joining a coalition of electors hoping to vote against Trump. He declined.

“I don’t think we should drag this election out any longer,” Vu said. “And can you imagine if the electors overturned the results? If we attempt to change them in any way, you’ve got these far-right elements that are just going to go haywire.”

Mark Hersch, a 60-year-old Chicago-based marketing strategist, joined a group known as the Hamilton Electors, who have been organizing efforts to contact electors and change their minds. Before the election, Hersch said, the most political activism he had ever undertaken was planting a yard sign.

He said he believes the goal to deny Trump seems reachable if not probable. Rather than persuade an entire country, he and his allies must find 37 Republicans willing to vote for someone else, a tipping point at which the responsibility of picking the president would shift to the U.S. House of Representatives. No one knows for sure how many are considering alternate votes; estimates vary from one to 25.

The GOP-controlled House could vote for Trump anyway, but those trying to flip voters say there is still value in taking a stand. Hersch said he was inspired to continue to flip electors by the movie “300,” which depicts an ancient Spartan army’s stand against a Persian force that outnumbered it 1,000 to 1.

“I would like to think we would be successful, but if not, we need to do all we could to prevent this man from being president,” he said. Then he modified a line from the movie: “Prepare your breakfast, and eat hearty, for tonight, we will go to battle. This isn’t 300, but 538.”

That “battle” has intensified as electors draw closer to their convening Monday. Joyce was getting 15 letters a day and 300 emails in the days after Nov. 8, but those numbers quickly increased to 50 and 3,000. Some of them have been form letters, others handwritten.

The letters came from Washington state and from China, stuffed with copies of the U.S. Constitution or Alexander Hamilton’s writing in Federalist Paper No. 68, which states that the meeting of the electoral college “affords a moral certainty, that the office of President will never fall to the lot of any man who is not in an eminent degree endowed with the requisite qualifications.”

On Thursday, Joyce received so many letters that the letter carrier just gave her a U.S. Postal Service bucket filled to the brim.

“I’m sorry this is happening to you,” Joyce recalled the letter carrier saying. While some electors have complained of harassment, Joyce shrugged off the mail and placed it all on a sofa decorated with American flag pillows.

“This is America,” she said in a phone interview. “People have a right to say what they want.” She said most of the messages were thoughtful.

On Friday, she said, her emails became more positive. The messages were from Republicans, thanking her for taking Trump to the finish line of an arduous process.

“How refreshing!” she said.

Although some Democrats (who have in the past five presidential elections lost twoin which they won the popular vote) and even Trump himself have questioned the necessity of the electoral college, many opposing Trump have said this election proves just how important it is.

Norman Eisen, a former ambassador to the Czech Republic who has served as legal counsel to the Obama administration, began calling electors to explain that their job is not necessarily to certify the results but to have a reasonable discussion over whether the public made the right decision.

For instance, Eisen, who focused on government ethics in Obama’s White House, noted that Trump could be violating a clause in the Constitution that prevents presidents from receiving gifts and funds from foreign governments; it is unclear whether his businesses do because he has not publicly disclosed his tax returns.

In Massachusetts, Republican operative and attorney R.J. Lyman said he didn’t want to harass anyone, so he used his connections to find electors who were willing to chat about the lessons he learned in American history class and at the dinner table. He became one of the few people in the country more willing to talk about Hamilton the man than about “Hamilton: An American Musical.”

The electoral college, he said he tells them, was “not intended to be a rubber stamp.” Otherwise, he said, the Founding Fathers would have tasked the responsibility to a clerk or simply used the popular vote as a way of choosing a president.

“I’m reminding them of their duty to think about their choice in a way that’s consistent with their conscience and the Constitution,” Lyman said.

So far, Lyman said, he has identified 20 electors who might be willing to vote “other than their party pledge.” He couldn’t name more than one publicly but insisted that more were out there.

Earlier this month, Chris ­Suprun of Texas became the first Republican elector in a red state that voted for Trump to declare, in a Dec. 5 New York Times column, that he would not cast his electoral vote for Trump. Suprun voted for Sen. Ted Cruz of Texas in the primary and said he left behind his wallet on Election Day and thus did not vote in the general.

Nonetheless, Suprun said, he was willing to vote for Trump in the electoral college until the candidate claimed with no evidence that millions of Clinton supporters voted illegally.

Suprun’s public stance has elicited death threats and hate mail, he said.

“As of yesterday, people are calling to say, ‘Get your ass together, or we’re coming for you,’ ” said Suprun, who was the sole Republican elector to ask for an intelligence briefing on Russia. “They are doing it with their own phone number, not even blocking the number. That’s not been surprising — look at what Trump says himself.”

Vinz Koller, a Democratic elector from Monterey County, Calif., said he read Suprun’s column and started thinking about his own role in the college. It inspired him to support a new theory: If he could persuade other Democrats to abandon their Clinton votes, perhaps he and Republicans could agree on a more conventional choice — a la Ohio governor and failed GOP candidate John Kasich — to vote for instead of Trump.

The plan seemed unlikely, he said, but Trump’s candidacy unsettled him so much that he felt he needed to try anything. California is one of 29 states that mandate electors vote for the candidate who won the state, so Koller sued to continue his plan.

“Frankly, this is hard and not something I do lightly,” he said. “I’ve been working in partisan politics a long time, and I don’t like voting against my candidate, but I never thought that the country might be unstable until now.”

On Thursday evening, he found himself in the Library of Congress. Strolling through its stacks, Koller sought a librarian with one request: Can I see the original Federalist Papers?

He looked to see Federalist No. 68, written by Hamilton to describe the need for the electoral college.

“We have been getting a civic lesson we weren’t prepared to get,” Koller said. “They gave us the fail-safe emergency brake, in case the people got it wrong. And here we are, 200 years later. It’s the last shot we have.”

MOSUL, Iraq — Hundreds of thousands of people who remain in this northern Iraqi city are struggling to find food and safe drinking water as the protracted offensive against Islamic State militants batters their neighborhoods.

When the battle began seven weeks ago, aid agencies feared that an exodus from the city would overwhelm already crowded camps. Instead, most people heeded government advice to stay in their homes as security forces advanced.

Now many of those residents lack even basic services, with water supplies cut by the fighting, and U.N. and government aid distributions unable to reach all of those in need. Some residents are moving from neighborhood to neighborhood in search of food or to escape the bombardment.

Meanwhile, in areas still controlled by the Islamic State, a siege by security forces is slowly tightening, pushing up food prices and causing shortages while the militants prevent people from leaving.

Iraq is struggling to meet the needs of 3.2 million people displaced over the past three years during fighting against the Islamic State. To limit the displacement from Mosul, the government airdropped leaflets over the city telling civilians to stay put.

But few commanders expect the battle to finish anytime soon, and the misery unfolding in Mosul is expected to worsen as winter sets in.

Reaching people inside the city is risky for humanitarian agencies, which also say they do not have enough aid to meet the need.

This month, Iraqi counterterrorism forces escorted a truck carrying bottled water into the neighborhood of Zuhoor, which had been retaken two days earlier. People quickly crowded around to grab whatever they could.

“Is there any food?” they clamored. “We don’t have any food.”

[The mounting death toll in Mosul forces questions about the battle plan]

Because of the shortages, some residents have decided to leave the recently reclaimed neighborhoods and move to others on the city’s edge that are better supplied.

Only people who end up in the camps are included among the official number of displaced — 100,000 people — and the United Nations says it has no way to gauge how many internally displaced are in the city.

Jassim al-Attiyah, Iraq’s deputy minister for migration and displacement, estimated that more than 150,000 are displaced within the city and that hundreds of thousands of others remain in their homes but still need aid.

“There is some aid, but it’s a big battle,” he said.

On the far eastern outskirts of the city, Haitham Mazin, 40, his wife and three children are living with a relative in Gogjali, where water and food are distributed more frequently, and some medical assistance is available.

Mazin had wanted his family to stay in their home in the Zahra neighborhood after the area was retaken by Iraqi security forces, but the food and fuel he had stockpiled ran out. He said that aid distributions were haphazard and that while some people with connections to security forces had received enough assistance to even sell some, other families, including his, had gone without.

Dependent on well water, which is not safe to drink, residents had fought when water supplies arrived, he said.

“We became like beggars,” he said. “The government at the beginning told us to stay home, but they didn’t provide anything for us.”

Half the direct assistance provided by the United Nations since the beginning of the operation for Mosul has been distributed to those in the city, said Lise Grande, the organization’s humanitarian coordinator for Iraq.

“We are very worried that we are going to run out of supplies,” she said. “We only have limited amounts of stocks, and if everyone near and inside Mosul requires help, we won’t have enough — not by a long shot.”

[Iraq has never seen this kind of fighting in its battles with ISIS]

The United Nations and its partners are providing food parcels to sustain families for a month — after which the government’s food-distribution system is supposed to take over. “We’re hoping this happens, because in many locations the first month is nearly over,” she said.

Younes Sabri, 30, left the recaptured neighborhood of Bakr this month with his mother and two children. There was no food, water or electricity, he said, and the mortar shells were still falling.

At first he had walked an hour each day to Gogjali in search of supplies to take back to his family, but then he had decided to move into the house of a friend in the neighborhood who had left for a camp when the area was engulfed in fighting.

“The humanitarian situation there was very bad. Even the basics were not available,” he said of his neighborhood.

But like others, he is wary of the camps, because once people are there, they are not allowed to leave, not even if their neighborhood has been retaken.

“People of Mosul have only two options,” he said. “Either stay inside and die because of the bombing or hunger, or go to the camps — to the prison. Either way, it’s a slow death.”

Attiyah, the government minister, cited “security reasons” for restricting the movement of those in the camps.

The government’s decision to try to keep people in their homes has slowed the battle, limiting the use of heavy artillery and airstrikes. Commanders are urging Iraqi Prime Minister Haider al-Abadi to allow them to move families out of their neighborhoods temporarily to quicken the battle, but that could add to the humanitarian burden.

For the moment, people are being given the choice of whether to stay or leave.

Attiyah said he expects the situation to worsen. Security forces have retaken neighborhoods on the eastern side of the Tigris River, which carves the city in half, but have not yet entered areas on the other side.

The situation in those Islamic State-held areas is also a “tragedy,” Attiyah said. “There is no water, no electricity, and a lot of the doctors have left.”

Instead of heading to the camps, some people have fled to western Mosul. When the fighting starts there, he said, they will have nowhere to run.
