The field for the Republican presidential nominee has just gotten smaller. Today, Rick Santorum has announced that he will be suspending his campaign.

Santorum was just behind Massachusetts politician Mitt Romney in the number of delegates he’s won, but his race to the White House is over, likely making it a competition between President Obama and Romney come this November.

According to the Washington Post:

Rick Santorum will announce Tuesday that he is suspending his presidential campaign, all but bringing to a close the 2012 GOP presidential contest and formally handing the nomination to Mitt Romney, according to an official close to the campaign.

Santorum is set to announce his withdrawal at a campaign event happening shortly in Gettysburg, Pa. — the site of the historic and pivotal Civil War battle.

The former Pennsylvania senator had been Romney’s top opponent, but he suffered a trio of defeats last week in Wisconsin, Maryland and the District of Columbia, and over the weekend his daughter, Bella, was hospitalized for the second time this campaign due to complications from a rare genetic disorder.

Santorum is currently second in the delegate race, but he would have to win upwards of three-fourths of the remaining delegates in order to secure the nomination.

Newt Gingrich and Ron Paul are still in the running, but just last week, Gingrich revealed that his campaign is millions of dollars in debt and that it’s been difficult for him to keep up with the spending abilities of Romney.

Update: Santorum is currently giving his speech in Pennsylvania, recounted his time as a candidate in the race. Watch here.
