We’ve heard about Republicans switching to Obama, but one of Obama’s own speech writers, who also wrote for Hillary and Edwards is leaving the Democratic Party. She writes:

The final straw came the other week when Samuel Joseph Wurzelbacher (a.k.a Joe the Plumber) asked a question about higher taxes for small businesses. Instead of celebrating his aspirations, they were mocked. He wasn’t “a real plumber,” and “They’re fighting for Joe the Hedge-Fund manager,” and the patronizing, “I’ve got nothing but love for Joe the Plumber.”

Having worked in politics, I know that absolutely none of this is on the level. This back and forth is posturing, a charade, and a political game. These lines are what I refer to as “hooker lines”—a sure thing to get applause and the press to scribble as if they’re reporting meaningful news…

The party I believed in wouldn’t look down on working people under any circumstance. And Joe the Plumber is right. This is the absolutely worst time to raise taxes on anyone: the rich, the middle class, the poor, small businesses and corporations.

Our economy is in the tank for many complicated reasons, especially because people don’t have enough money. So let them keep it. Let businesses keep it so they can create jobs and stay here and weather this storm. And yet, the Democratic ideology remains the same. Our approach to problems—big government solutions paid for by taxing the rich and big and smaller companies—is just as tired and out of date as trickle down economics. How about a novel approach that simply finds a sane way to stop the bleeding?

That’s not exactly the philosophy of a Democrat. Not only has this party belittled working people in this campaign from Joe the Plumber to the bitter comments, it has also been part of tearing down two female candidates…

Governor Palin and I don’t agree on a lot of things, mostly social issues. But I have grown to appreciate the Governor. I was one of those initial skeptics and would laugh at the pictures. Not anymore. When someone takes on a corrupt political machine and a sitting governor, that is not done by someone with a low I.Q. or a moral core made of tissue paper. When someone fights her way to get scholarships and work her way through college even in a jagged line, that shows determination and humility you can’t learn from reading Reinhold Niebuhr. When a mother brings her son with special needs onto the national stage with love, honesty, and pride, that gives hope to families like mine as my older brother lives with a mental disability. And when someone can sit on a stage during the Sarah Palin rap on Saturday Night Live, put her hands in the air and watch someone in a moose costume get shot—that’s a sign of both humor and humanity.

She sees the long term train wreck ahead.
