The Florida primary may not be over just yet because the Newt Gingrich campaign is gearing up to challenge the primary based on the Republican National Committee's rules, according to a Fox News report.

The RNC's rules state that no winner-take-all primary may be held before April 1 and Florida happens to be a winner-take-all state.

The winner of Florida's primary, Mitt Romney, was expected to gain all 50 of the state's delegates, but the Gingrich campaign demands to split up the delegates based on percentage, the report says.
