You can't visit the NY Times opinion page without someone opposing Obama (a good chunk of Americans) being called a racist (a very serious accusation), and they're dropping in credibility faster than the SPLC. Reason examines this phenomenon in American history in a very interesting piece:
A similar dynamic is at work in 2009. When pundits weave a small number of unrelated incidents into a "pattern" of crime, then link it to the rhetoric of Obama's opponents, it becomes easier to marginalize nonviolent, noncriminal critics on the right, just as a red scare makes it easier to marginalize nonviolent, noncriminal figures on the left.Admittedly, there been an uptick in crazy lately. After all, shoddy economies and Americans coming home in body bags tend to produce a more extreme politics, and right now America has both. But, the lame attempts to discredit Obama critics as being a pack of racist, barnyard yokels is pretty transparent partisan politics.
