Rick Santorum suspends presidential campaign

WASHINGTON, Feb. 3 (UPI) -- The Republican presidential field continues to thin out as former Pennsylvania Senator Rick Santorum dropped his bid for the White House on Wednesday.

CNN reported that Santorum will announce his departure from the race Wednesday evening. The Washington Post said Santorum will make "two major announcements," one of which is likely to be an endorsement for another candidate. Since Santorum was one of the candidates to attend Donald Trump's campaign event to benefit veterans last week, some are speculating the real estate mogul will get his support.

Santorum's 2016 campaign failed to gather the steam it did in 2012. That year, he was declared the winner of the Iowa caucuses, with Mitt Romney, the eventual nominee, a very close second. On Monday night, Santorum failed to garner a single delegate, and got just one percent of the vote.

The former senator was not likely to get another chance to debate, since ABC News announced it would not hold an undercard debate on Feb. 6 for low-polling Republican contenders.

The end of his campaign is not a total surprise. As we reported Monday evening, Santorum's campaign had no events scheduled until May, just before Iowa holds its official primary.

On average, Santorum polled at less than one percent nationally, according to RealClear Politics. He suspended his campaign the same day that Sen. Rand Paul, R-Ky., announced he was suspending his to focus on his Senate re-election race.
