The only reason to have Rubio on board is if Rubio could help deliver Florida. However, Rubio is despised in his home state (he's not running for re-election to the Senate because he wouldn't get re-elected) and therefore brings absolutely nothing to the table. The notion that Rubio represents the "Future of the GOP" is just a bunch of self-serving hype from the RNC.
Trump WILL deliver Florida on his own he IS very well liked in FL. Hillary is a horrible candidate I believe ANYONE could beat her she is just a despicable LIAR all of this talk about how well she WILL do is just BS!!! For goodness sake BERNIE is KICKING her ass!!!
