Listening to Hardball right now and Joe Trippie, of MSNBC, is trying to claim that liberals (now called "progressive") dominate the blog. What a laugh. Anyone familiar with the blog, for good or bad, know that it's largely a conservative medium.
The the top blog sites are almost exclusively conservative. There's a handful of exceptions but it's not very close.
It's always interesting to see guys like Chris Mathews trying to argue that the blogsphere is somehow leftwing simply because the Democratic Underground (not a blog site btw) is better at flooding the MSNBC on-line polls than conservative sites are. Flooding on-line polls is..well so 1990ish.
