Drudge says it’s 52-48 Hillary as of 5 p.m. ET; Fox News should have exits by demographic group at 6 p.m. I can’t find the data Marc Ambinder’s citing but I’ll take his word on it: “25% of Clinton supporters say they’d vote for McCain in the general election; 17% of Obama supporters say they’d vote for McCain in the general election.” Plus, a whiff of Chaos from the AP:

One in 10 voters changed their party registration since the start of the year so they could vote in the hotly contested primary, which was open only to registered Democrats. About half of the party-switchers had been registered Republicans and the rest had been unaffiliated with either party.

One in five say race was a key factor in their vote, another one in five say gender was. Standby for updates galore.

Update: Here’s the complete exit poll data set from CNN.
