Pollster Stanley Greenberg and political operative James Carville, last year, reported on a series of focus groups with older, white Republicans in Georgia. They were on a quest to understand the hardcore opposition to Obama. Is it racist? They concluded no. They admonished us to "Get over it." The animus to Obama, they claimed, is "based in the same unwavering, bedrock conservative principles that have always led them to oppose liberal policies. Some of their subjects even claim to be post racial-"proud" there is an African-American president. I have my own informal focus group, and I'm not buying it.
