Via TVNewser and following up on Nate’s post, this profile of Tony Snow in the Cincinnati Post sheds some light on why CNN is having a hard time keeping top conservative commentators on board:

Snow found it interesting that CNN recently hired some big-name conservative pundits, including Glenn Beck to host a CNN Headline segment, and former education secretary William Bennett and former Congressman J.C. Watts.
“It’s clearly an attempt to respond to the challenge Fox has laid down,” Snow said.
“When I was at CNN, they tended to treat conservatives as knuckle-dragging morons. I’ll never forget the time they invited me to come on ‘Crossfire’ as a host and the topic was David Duke – they wanted me to come on and defend him. I said, ‘I’m sorry, you got the wrong guy.’”

We’ll know whether CNN has changed the way it treats conservatives if they keep letting Bill Bennett shake things up.
