As snugs said, they probably can't field the top names every week, or the impact would be deluted. So, we are back to the question of how to get the articulate, pro-troops senators onto the shows. Heck, unless you watch Fox, you would never see Norm Coleman, and look at all he has uncovered about the Oil for Food scandal!
Maybe Coleman and Inhofe and Kyl should start running around with Brad Pitt and Angelina Jolie. It seems they get much more press than the President. HA!
It seems the more useless the Senator is the more he is on the MSM. Look at "the swimmer", and Biden, Rockefeller. Are there three more useless Senators in the entire US Senate? Oops, I forgot Mikulsky,Boxer,Jeffords,Murray. Oh Forget it, there is too much competition for Useless.
