Experience: Rubio spent nine years in the Florida House of Representatives, serving as speaker for the final two, before running for the U.S. Senate.
Pros: Rubio has been a national Tea Party favorite and triumphant underdog since his bid for the U.S. Senate began in 2009. Though he initially trailed his opponent, Republican Governor Charlie Crist, Rubio won the general election by double digits in November 2010. The son of Cuban immigrants, he’s also a solid choice for appealing to immigrant voters.
Cons: Despite his popularity among Tea Party voters, Rubio is often cited as failing to excite conservative voters across the board.
