I think this is a blunder on CNN's part also.
Viewers are leaving them in droves not only because of bias, but more importantly because of tone.
The left, finding itself in the unenviable position as having been proven wrong on ALL its predictions to date, having positioned themselves to have to root against America in the war, and root for the economy to fail, now resort to shrill, nails on chalkboard, void of substance rants and accusations, and I think that, other than die-hard Che Guevara types,even some left of center grow tired of it quickly.
CNN is so pessimistic, and the folks at Fox are having a ball.
