Who Benefits from Rand Paul and Rick Santorum Dropping Out?

I check last month's PPP poll in New Hampshire which has a handy dandy crosstab with that data.  Rand Paul supporters seem to either go mainly to Cruz or to undecided (I guess they might stay home or vote for the Libertarian candidate).  Rick Santorum supporters (which has to be a small handful) will go to a few places but Rubio will get 44% of them and Cruz will get 20% (as would JEB and Fiorina).  It's kind of funny how Santorum is thought of as so far right but really he has mainly establishment-minded supporters.
