There will be a major Establishment candidate and I expect that to be Rubio—so I think we’ve yet to see anything near his peak.
Add up the poll #’s for the gOpE (Rubio, Bush, Kasich, Christie). The other non-outsider (Huck, Santorum, Paul, Jindal ...) votes will mostly go to an outsider not the gOpE. Rubio has very limited upside.
