So far, things are looking better than expected for Obama. He's got a big win in GA and CT, NJ, and TN (all states where Clinton was expected to run well) are too close to call.
Update: MSNBC just called TN for Clinton. That probably restarted a few hearts in the Clinton campaign.
On the Republican side, Romney seems to be running better than expected, but given the winner-take-all nature of the GOP primaries, it remains to be seen how much good it does him.
