From his excellent take on JournoList in the Wall Street Journal:

Until JournoList came along, liberal journalists were rarely part of a team. Neither are conservative journalists today, so far as I know. If there’s a team, no one has asked me to join. As a conservative, I normally write more favorably about Republicans than Democrats and I routinely treat conservative ideas as superior to liberal ones. But I’ve never been part of a discussion with conservative writers about how we could most help the Republican or the conservative team.
My experience with other conservative journalists is that they are loners. One of the most famous conservative columnists of the past half-century, the late Robert Novak, is a good example. I knew him well for 35 years. He didn’t tell me what stories he was working on nor ask what I was planning to write. He never mentioned how we might promote Republicans or aid the conservative cause, nor did I.
What was particularly pathetic about the scheme to smear Mr. Obama’s critics was labeling them as racists. The accusation has been made so frequently in recent years, without evidence to back it up, that it has little effect. It’s now the last refuge of liberal scoundrels.
The first call I got after the Daily Caller unearthed the emails involving me was from Karl Rove. He said he wanted to talk to his “fellow racist.” We laughed about this. But the whole episode was also sad. I didn’t sputter at the thought of being called a racist. But it was sad to see what journalism, or at least a segment of it, had come to.
