The reality is that Rubio has even less substance than Ben Carson and it will soon become apparent as he moves into the spotlight.
Yeah, I know, either Carson or Rubio still has waaaaaaaay more substance than BO, but neither is a Democrat.
The main thing which is clear from the more recent polls is that Ben Carson’s star is fading and Cruz and Rubio are both fighting for second place.

Of course anything can happen...but more than likely no one is going to catch Trump & he will move into the mid 40%. Cruz & Rubio will continue fight each other for second place & stay around 15% & Carson will be in single digits soon, along with the rest of the pack. I don’t see any of the main stage contenders dropping out until after New Hampshire or beyond.
