1237 - 171 = 1066
I wouldn't at all be surprise if/when Trump gets to 1066+ delegates that he announces that Marco Rubio has agreed to be on the ticket as the VP candidate. Think big. (as opposed to small hands)
If Cruz, somehow, gets 1066+ delegates ... who knows?
I noticed a lot of suggestions of Rubio as VP ended up as thread-enders, lol.
