If so.....WHY ?
Ideally, my favorite candidate would probably be Ted Cruz. Realistically, however, I think the GOP needs someone who can bridge the gap between the two main wings of the Republican Party (i.e. Establishment Republicans and the Tea Party). Anyone else is very likely to lose the general election to Hillary Clinton, in my opinion.
And for Hillary Clinton to be president for the next four years--perhaps even the next eight years--is a thought that I do not wish to entertain...
Pssssssssssssssst....Rubio won't even win the primary in Florida!
