Obama kicks things off with a huge win in Georgia.

UPDATE: Obama has taken Delaware and Illinois. Clinton has taken Arkansas, Tennessee, Massachusetts, New York, and New Jersey.

McCain’s won Delaware, Connecticut, Illinois, and New Jersey. Romney’s won Massachusetts and Huckabee, somewhat to the pundits’ surprise, is kicking a little ass in the South, taking Arkansas, Alabama, and West Virginia.

The story thus far, as far as I can tell: McCain’s still the presumptive favorite, but not doing nearly as well as people thought. Huckabee is his secret weapon, siphoning conservative votes from Romney. Clinton is doing extremely well, taking the Mass. and NY prizes despite late Obama surges.

UPDATE: The latest, via TPM:

CLINTON: AR, MA, NJ, NY, OK, TN
OBAMA: AL, CT, DE, GA, KS, IL, MN, ND, UT
HUCKABEE: AR, AL, WV
MCCAIN: CT, DE, IL, NJ, NY, OK
ROMNEY: MA, UT

The Mass. loss was a real blow to Obama. I think he’s going to fall short of the hype and lose a little momentum. Calif. is huge, huge, huge, and I hear Latinos are going heavily to Clinton, so things don’t look good for him there either. Big night for Clinton.

Also, holy crap, Huckabee just won Georgia. He is blowing away expectations. Can you say VP?

UPDATE: Clinton takes Arizona — another blow to Obama. Looks like the delegate count is going to be fairly close. It all comes down to California.

UPDATE: They’re calling California for Clinton. NPR says Clinton is about 20 delegates ahead of Obama — that’s close.

Also: Sen. Barbara Boxer (D-Calif.) is a superdelegate; she pledged to vote for whoever won Calif., so she’s voting for Clinton.

UPDATE: The Mittster picked up a run of late states — ND, MT, UT — but McCain picked up Calif., so it still seems like he’s the prohibitive candidate.

UPDATE: Kos says they called Missouri wrong — Obama is in fact the winner.

UPDATE: Just noticed that Clinton called out beating the “climate crisis” in her (strong) speech tonight.

UPDATE: Alaska goes to Obama. As did, it turns out Missouri. I can’t find a definitive delegate count, but there are rumors around that Obama might even have a lead.

UPDATE: Sounds like Romney might be dropping out in the next few days.

UPDATE: The popular vote on the Dem side was incredibly close — something like 49% to 48%. The race is a dead heat. Harold Meyerson has an insightful look at where the race goes from here.
