The Republicans favorite symbol for what they imagine ordinary Americans to be, Joe the Plumber, has turned his back on the GOP. And while he has not taken the additional step of registering as a Democrat, the blow will surely come as a shock to Sarah Palin and the rest of the right’s lunatic fringe. From Time:

Big Government is never popular in theory, but the disaster aid, school lunches and prescription drugs that make up Big Government have become wildly popular in practice, especially now that so many people are hurting. Samuel Wurzelbacher, better known as Joe the Plumber, tells TIME he’s so outraged by GOP overspending, he’s quitting the party – and he’s the bull’s-eye of its target audience. But he also said he wouldn’t support any cuts in defense, Social Security, Medicare or Medicaid – which, along with debt payments, would put more than two-thirds of the budget off limits.

As the defections accelerate, the GOP will soon be left with only Carrie Prejean, Ted Nugent, and an ocean of dittoheads, to lead their trek back to relevancy. Of course, this could all be unfolding exactly as planned by Republican National Committee chairman, Michael Steele.
