TAMPA, Fla. (CBS Tampa) -  Newt Gingrich may challenge the results of the Florida Republican presidential primary so that delegates would be given to candidates proportionally.

The results of the Tuesday primary presumed Mitt Romney the winner of Florida’s 50 delegates, but there is a rule that could change the results of the contest.

According to the Republican National Committee’s rules, winner-take-all contests cannot occur until April 1, 2012.  Fox News reported that the Gingrich campaign would pursue having the RNC rules apply to the Florida primary results so that the delegates would be awarded according to the percentage of votes each candidate received.

A Gingrich campaign memo cited the RNC rule and stated that “it would appear that the issue of whether Mitt Romney indeed won all 50 delegates in the Florida primary remains an unsettled question.”

Mitt Romney won 46 percent of the Florida vote while Gingrich won 32 percent.  Rick Santorum received 13 percent and Ron Paul 7 percent.
