If anyone but Jeb gets the nomination, I could see Rubio getting the VP slot. We really need Florida.
No one but Jeb would want Rubio as VP but as you point out, that is geographically bad.
Rubio is a blocker for Jebster, same as Graham. I’ve seen this playbook before.
Fred Thompson played blocker for McCain.
I don’t think Jeb could choose Rubio as his running mate if he gets the nomination, since they both live in the same state. Remember that Dick Cheney moved to Wyoming when George W. Bush chose him as his VP because Cheney was also a resident of Texas
