No, Ms. Maddow shouldn't leave the MSM, but we already have her, steward and colbert, and they do some important work. But we don't need another soft-ball pitcher. We need someone to play hardball, and that's just not going to come from the corporate media. Corporate America will not undermine itself.
The problem with "in the middle" is that it's the middle of power and firmly in the right wing, not the middle of the population. I think that real change and momentum will have to come from outside the system, real grassroots stuff, which is what Cenk's doing right now.
