Howie Kurtz does this almost every single week, and he's not alone. He pits one or more conservative pundits or reporters for right wing publications against journalists for mainstream newspapers.
Here's his take on that:
Bedford, Tex.: Hi, I watched "Reliable Sources" on Saturday and I was curious why
there was a conservative (Laura Ingraham) but no liberal pundit. I consider Roger
Simon and Dana Milbank to be beat reporters and not liberal pundits.
Howard Kurtz: They're certainly more liberal than Laura Ingraham. I refuse to play
the Crossfire game of matching up partisan liberals and conservatives and let them
go at each other.
The liberal media rears its ugly head once again.
