More than anything, this is turning out to be a moment of truth for the left. Will they continue to stand by Obama, suggesting that their opposition to "Bush's war" was just an unprincipled cover for their hatred for a socially conservative, Republican President? Or are their convictions about (not) fighting terrorism strong enough to compel them to speak out even against a President they once idolized?
It will be interesting to see. The fact that MoveOn.org has scrubbed their site of the attack ad they took out on Petraeus back when he was a Bush nominee isn't encouraging for those who believe in the left's purity.
