Two critical -- and underreported -- points.  First, the liberal bloggers' power was a bit of an illusion.  It stemmed from their role in helping otherwise underfinanced candidates raise lots of small contributions and become competitive financially.  When someone like Obama comes along and knows how to raise the same kind of grass roots money without them, it minimizes their influence -- something I happen to think is a very positive development.

Second, and this is anecdotal.  I myself thought until about two months ago that the lefty bloggers were influential.  Then, it hit like a ton of bricks that their influence is minuscule.  The incident?  The infamous "Donny McClurkin" incident.  The lefty bloggers and commenters were on fire with indignation over it, and I was extremely worried about it, being an Obama supporter.  Then after days of indignation on the blogosphere, it turned out the McClurkin story had ZERO influence on the race.  

It is fitting that Edwards is excited about lefty blogger support for him, because he's been under the illusion for a while now that there is a large audience for his agitprop, knownothingism.  I've grown to detest Edwards.  He was long my second choice, but for the last three months he's been my last choice -- behind Hillary, Biden, Dodd, and even the hapless Richardson.
