Is This Obama's Macacca Moment?

Senator George Allen was considered by many a promising possible candidate for the Republican presidential nomination in 2008. His 2006 opposition for the U.S. Senate race in Virginia, James Webb, employed a person of Asian descent to follow Allen around with a video camera. Allen got pertubed and used a slur in reference to the Asian cameraman, referring to him as Macaca. Allen then was branded as a racist, and lost his reelection bid. That one state provided the margin by which the U.S. Senate turned from a Republican to a Democrat majority.

Now, Barack Obama, in a closed door fund-raising speech to a group of wealthy liberals in San Francisco, referred to rural Pennsylvanians in these words:

"You go into some of these small towns in Pennsylvania, and like a lot of small towns in the Midwest, the jobs have been gone now for 25 years and nothing's replaced them. And they fell through the Clinton Administration, and the Bush Administration, and each successive administration has said that somehow these communities are gonna regenerate and they have not. And it's not surprising then they get bitter, they cling to guns or religion or antipathy to people who aren't like them or anti-immigrant sentiment or anti-trade sentiment as a way to explain their frustrations."

Is this going to be Barack's Macacca moment?
