I don't think so, as long as Rubio is in check, and or Jeb he will stay out. It's if either of those two make a big push then he will get in.
Carson, the other dude who got less than 1% ,and a few others should drop, Fiorina included but she still thinks she is important. She will hang through S.C.
cruz/sanders is the race bloomberg wants since it desperately needs a moderate. he likely wont run if its rubio/clinton.
Chris Matthews, a Clinton apologist for the most part, has finally declared that Hillary is in big trouble and on the defensive and that Sanders is not to be stopped and a powerhouse and he isn't sure Hillary can do it with the speech she gave tonight.....my jaw dropped
remember all this 'Clinton doesn't want to face Rubio' talk....well it's time to consider who would beat Sanders
