Super Tuesday may be the biggest event of the political season so far, but that doesn't mean everyone knows exactly what's on the table. In all, there are 419 delegates up for grabs between 10 states.
A portion of Wyoming will also be voting today, but because of the complicated process, few organizations will be reporting the results.
While the states participating today offer 437 delegates total who will help determine the GOP nominee, "superdelegates" and the non-binding results of some states make the actual numbers a candidate can win a little less clear-cut (the Romney campaign is going with a 391 delegate count and we're counting 419). However, there's still enough on the table for the results to potentially change the likelihood of a candidate's nomination. By some counts there are more delegates available than there have been in all the preceding primaries and caucuses combined.
Scroll down for a brief state-by-state Super Tuesday breakdown, and real-time results once they begin to be reported.
Newt Gingrich represented Georgia in Congress for 20 years and led by a decent margin in the polls leading up to Super Tuesday. Gingrich has even said that he must win Georgia simply to remain credible in the race for the nomination.
Ohio is a contest to watch. Romney has held a small lead going into the primary, but Rick Santorum has been biting at his heels here. A classic swing state, winning Ohio handily could be a real vote of confidence for the victor.
Romney, the state's former governor, is expected to walk away with Massachusetts. Romney did not seek re-election in 2008, but instead pursued the presidency. Prior to this year's primary, he's held close to two-thirds of the vote in the state, according to polls.
North Dakota Caucus
With little polling in the state, North Dakota appears up for grabs. However, the Keystone XL pipeline has been a major issue in the region, and Romney's campaign chair in the state, Sen. John Hoeven, has been a strong proponent of the project. His influence may have an impact.
Idaho is very unclear. Romney began running ads in the state late, and Ron Paul has bashed the former Massachusetts governor in the state as part of his caucus-centric strategy.
There isn't much of a focus on Vermont, as it holds only a little bit of a boost for the winner. Romney's popularity in the northeast may be enough to secure the state, though if he doesn't claim 51 percent of the vote, he won't receive all of the state's delegates.
Gingrich and Santorum aren't on the ballot in Virginia, which pretty much guarantees victory for Romney. However, polling has suggested that the state would have hosted a much tighter race if Santorum were on the ballot.
Romney and Santorum have been expected to battle it out in Tennessee, and while the former Pennsylvania senator has held a lead in the polls there, the race appears to be statistically tied heading into Tuesday. A win for Romney would be considered an upset in such a conservative state.
Oklahoma is considered a test of conservatism, and as a result Santorum has led handily in the polls going into the primary. If a conservative candidate can't win there, there would seem to be little hope on the national stage.
Romney won Alaska in 2008 and is expected to do the same in 2012. Former Alaska Gov. Sarah Palin has not endorsed a candidate for the GOP nomination, despite some vocal support for Gingrich.
