Pure conjecture. Trump has been leading the polls for six months approaching 30% in a 16 person field. Trump has more crossover appeal than any of the Reps. His base is solid. No one has yet approached Trump's "ceiling" or floor for that matter. As candidates drop out, where will the support go?

Rubio was part of the Gang of 8 bills pushing the Rubio-Schumer amnesty bill. He is a tool of the Chamber of Commerce pushing increased H-1B visas. If he is the nominee, I certainly will not vote for him.

Not to Trump. If you are talking about Trump vs Clinton you may have something, but Trump is a very well known quantity. His ceiling in the GOP is pretty much where it is.

I venture to say, based on the polls, that 50-65% of Republicans cannot stand the man.
