The post-VP debate media coverage is still overly kind to Biden and Obama, but they're easing up a bit on Romney and Ryan. Have you noticed? I've seen and heard more positive coverage for the GOP ticket in the last few days than I had in the last few months together!
My guess is now that some swing states are solid for Romney and a few blue or purple states are leaning Romney, the media is scrambling to make themselves relevant. They're so out of touch with America, they didn't even know until now that Romney could be a real threat to Obama. I think they blame the losses in the media-favored polls (skewed unrealistically Democrat) on Obama's debate performance, even though the movement towards Romney really started a little earlier according to more reputable polls like Rasmussen.
A lot of conservative sites have been pointing out the obvious disdain of fly-over country in media treatment (and Democrat treatment, same thing). They seem not to care that middle America is suffering. At all. That was further illuminated by Biden's attitude in the VP debate. Juxtaposed by Wall Street having record gains thanks to the Feds, and it's clear that Obama/Biden care more about their bank accounts than the people of American. QE1, 2, and now 3 are all responsible for gains on Wall Street but higher living costs for the rest of us.
This movement towards Romney lasting more than a couple days spells trouble for Obama, to be sure. The media hates to be on the wrong side of history. This also tells me that the media doesn't think Obama can redeem himself in the next two debates.
