Ron Paul's campaign has also complicated matters. Though the libertarian-leaning Texan congressman has not yet won a single state's popular ballot, he is trying to build up a large number of delegates to take to Tampa. In caucus states, where complex rules mean the number of delegates assigned to a candidate can outweigh their score in the popular vote, Ron Paul's campaign is working hard to win as much support as possible. That could see him amass a body of delegates in Tampa that far exceeds his standings in the polls and makes a contested convention, with no one having enough support to secure victory, more likely.

Former Florida governor Jeb Bush announced his support for Mitt Romney’s presidential bid this morning, a major boost for the former Massachusetts governor as he seeks to rally the party behind his candidacy.

“Congratulations to Governor Mitt Romney on his win last night and to all the candidates for a hard fought, thoughtful debate and primary season,” Bush said in a statement released by his office on Wednesday morning. “Primary elections have been held in thirty-four states, and now is the time for Republicans to unite behind Governor Romney and take our message of fiscal conservatism and job creation to all voters this fall. I am endorsing Mitt Romney for our Party’s nomination.”
