It's official: John McCain has exhumed the body of Lee Atwater and breathed life into it.

Atwater was Karl Rove before Rove was Rove. (Actually, he was a mentor for Rove.) As the GOP's top strategist in the 1980s, Atwater--accused often of relying on unethical and dirty tricks--perfected the mean and nasty politics of resentment and, thus, helped elect George H.W. Bush president.

One of McCain's latest ads would make Atwater proud. The main line of the ad, which features Joe the Plumber, is this:

Obama raises taxes on seniors, hard working families to give "welfare" to those who pay none.

At Wednesday night's debate, McCain accused Obama of engaging in class warfare. But this is real, diehard class warfare, with McCain trying to persuade middle-income Americans that Obama will take money away from them to dole out to those on welfare. You can do the racial math yourself.
