If you listen to Rush, Sean, Laura, Levin - have the Drudge Report open at the same time, and compare the topics they start the show with, to what Drudge has up. Nine times out of ten, you won't hear them bring up a thing that's not already getting play in the MSM.
Rush is better than the rest, because he'll take topics out of the print media - you hear him do it all the time. Sean also, once in a while.
Point is, though, these guys all use the MSM as their filter. Not in the MSM - ain't gonna pass inspection on their show.
What pains me is that the talkers fail to see that many stories work their way up from internet forums, to blogs, to online news outlets, then into the MSM, and onto talk radio.
You'd think that by now, the big talkers would have caught on to the fact that citizen journalists are leading the way and breaking the biggest stories in the news, but no. Unless a story has the official MSM stamp of approval, it's "just a story off the internet".
I think the BC controversy is why Howard Dean high-tailed his DNC chair shortly after the election.
