UPDATE: Mitt Romney won Virginia in an unsurprising landslide. Click HERE for more details on the results.

--

Virginia is one of 10 states that will be holding its Republican presidential contest Tuesday night on one of the most important and revealing evenings of the primary.

The Old Dominion is in a unique situation, however, because only Mitt Romney and Ron Paul qualified for the ballot. House Speaker Newt Gingrich and ex-Pennsylvania Sen. Rick Santorum did not collect the required amount of signatures by Virginia's deadline and will not get a chance to win any of the state's 46 delegates. Although the two candidates--as well as former candidates John Huntsman and Rick Perry-- sued the state for unfair rules, a judge still rejected them in January.

Romney will likely win the state by a landslide. According to a recent NBC News/Marist poll, Romney had the support of 69 percent of voters while Paul had the support of 26 percent of voters.

Virginia is an open state, meaning that any state resident can vote in the primary, regardless of their party affiliation.
