Recently retired Bush adviser Dan Bartlett
talks about conservative blogs in an interview with Texas Monthly
That’s what I mean by influential. I mean, talk about a direct IV into the vein of your support. It’s a very efficient way to communicate. They regurgitate exactly and put up on their blogs what you said to them. It is something that we’ve cultivated and have really tried to put quite a bit of focus on.
That's why the conservative blogosphere isn't as powerful or interesting as the liberal blogosphere: because usually they're saying the same stuff the Republican establishment is saying. There already is a Republican establishment, so their blogs don't fill any gap. The lefty blogosphere has a very critical stance towards the Democratic establishment, and says things that you generally don't hear from Democratic leaders. It's powerful because it addresses a need that our political leaders aren't paying enough attention to.
