I think some of the media is finally going after the intergrity of the presidentail candidates. I think the Biden interview in Florida and the Obama campaign snubbing a local station in the afternath.
Some is, but I would question whether most of the media is, even Fox (its noticeable that the rest of the Murdoch press (that isnt in the US) is rabidly pro-Obama) which TBH seems to be just repeating what is being said on various blogs rather than doing its own digging.
In any case criticism of Biden, Obama and their campaign strategies is nowhere near the level that was aimed at Palin, even though she has made about a tenth of the gaffes that Biden has.
