FILE - In this Aug. 30, 2012, file photo, Florida Sen. Marco Rubio addresses the Republican National Convention in Tampa, Fla. Relieved to see the long, costly 2012 presidential race end?

Republicans hope Romney will be crowned the new GOP chief _ but a crop of would-be candidates are at the ready in case he loses Tuesday, among them: Florida Sen. Marco Rubio and Wisconsin Rep. Paul Ryan. (AP Photo/J. Scott Applewhite, File)
