I don't think Trump wants Rubio in his administration...but I think Cruz would offer Rubio just about anything...except VP...in exchange for his delegates.
“Ironically Rubio is helping Trump by staying in. Most of his votes would go to TC if he dropped out.”
Yes, I believe so, and have been saying this for some time. If the non Trump repubs really want to beat Trump in FL, the only way is for Rubio to drop out by tonight, and Cruz and Rubio to go forward as a Cruz/Rubio ticket. The vast majority of Rubio’s support would go to Cruz and the synergy of their alliance would also raise Cruz’ vote pull in FL.
