The four remaining Republican presidential candidates competed in nominating contests in Alabama, Mississippi and Hawaii on Tuesday, with 101 delegates up for grabs.
Both the Alabama and Mississippi primaries proved to be the night's most interesting. Mitt Romney, Newt Gingrich and Rick Santorum were in a virtual dead heat leading up to Tuesday, with Ron Paul trailing his rivals. For Romney, the primaries were a chance to prove he could appeal to southern voters. For Gingrich and Santorum, Tuesday was another round in their ongoing battle to be the contest's most conservative candidate.
Although the Hawaii caucus was almost entirely overshadowed by the primaries in the South, there was at least one candidate who had high hopes for the Aloha State's 17 delegates. Paul, the only remaining candidate who had yet to claim a win, hoped to put an end to his long string of losses with a victory in the Pacific.
Here's a look at the night's biggest winners and losers.
