This time in Charlotte:

Even as he accused Republican Mitt Romney of gunning for the middle-class with plans to raise their taxes, Vice President Joe Biden Tuesday inadvertently gave ammunition to GOP critics.

“How they can justify raising taxes on the middle class that has been buried the last four years?” Biden asked more than 1,000 supporters at the N.C. Music Factory. “How in the Lord’s name can they justify raising their taxes with these tax cuts?”

I’m actually amazed that the Uptown Paper of Record led with yet another VP gaffe. Of course the Obama campaign’s walking it back, saying it was the evil Bush administration that buried the middle class. Whatever. One thing’s for sure —Obama sure hasn’t done anything to exhume the middle class.
