An excellent sum up:

Do you think if Barack Obama had left his seriously ill wife after having had multiple affairs, had been a member of the "Keating Five," had had a relationship with a much younger lobbyist that his staff felt the need to try and block, had intervened on behalf of the client of said young lobbyist with a federal agency, had denounced then embraced Jerry Falwell, had denounced then embraced the Bush tax cuts, had confused Shiite with Sunni, had confused Al Qaeda in Iraq with the Mahdi Army, had actively sought the endorsement and appeared on stage with a man who denounced the Catholic Church as a whore, and stated that he knew next to nothing about economics — do you think it’s possible that Obama would have been treated differently by the media than John McCain has been?  Possible?

And — this is fun to contemplate — if Michelle Obama had been an adulteress, drug addict thief with a penchant for plagiarism — do you think that she would be subject to slightly different treatment from the media than Cindypills McCain has been?  Anyone?
