At about 3:05 in this YouTube video excerpt from the Rachel Maddow show on MSDNC, Pennsylvania Governor Ed Rendell lets it slip:
I look at these McCain rallies in Pennsylvania, and he says 'Barack Obama's going to take your wealth.' But they don't have any wealth.
Right, Guv! It's the wealthy who support Obama. The average Joe the plumber, Mike the mechanic, and Florence the flower shop owner support John McCain because they don't have any wealth. That's why they can't afford for Obama to tax all the profits out of their small business aspirations. They can't afford for Obama to let the Bush tax cuts expire. The great majority of average Americans can't afford an Obama-nation!
