So what? He should be. He's clear that he likes bloggers who doggedly support the conservative cause. That's utterly unsurprising.
Here's Glenn's response, but, really, no response is needed. Glenn's blog is compulsively readable because it's not predictable and it's not partisan.

I'm looking for interesting things to read and talk about, not ways to keep excited about things I've already decided I want to be excited about.
