A seam of online middle-class resentment?  

Apropos of Dean's impressive internet campaign take, EJ Dionne suggested today on This Week that the internet is doing for liberalism what talk radio did for conservatism 10 years ago. I wonder how others feel about this. If for instance we were in the middle of a Republican primary right now, would some candidate on the Right have demonstrated similar internet prowess? A year ago the blogosphere seemed to be dominated by conservative and libertarian ideologies; now this seems to be less true, although there isn't really a good metric for this kind of thing. I definitely don't have the sense, though, that the liberal line lights up cyberspace the way conservative bluster blares on my AM dial.
