It's incredibly biased (of course) and cites the SPLC (of course), but it's still worth a read, I think. Here's an excerpt:

The day after Obama's blowout win in Wisconsin, for instance, the home page of the poisonous Vanguard News Network featured stories on Serbian nationalism, home schooling, Holocaust-denial, and Pat Buchanan--yet nothing about Obama. It turns out that, although the white right certainly has no love for Obama, its hatred of him is muted--and directed less at Obama himself than at other nefarious forces behind him.
