This is analysis, not advocacy:
If Trump is the nominee there’s a good chance he picks Rubio as his VP.
It potentially helps Trump with Hispanics and Floridians (though by how much, is an open question). It gives him a Washington/establishment insider on the ticket (and can be seen as a sop to GOPe [I’ll keep your boy Marco around and train him for when he’s actually ready to run]). Similarly, Rubio is likely to be a “good soldier” who will say what Donald wants. It’s a nice finger in the eye to Jeb that Trump picked the “uppity kid” who wouldn’t wait his turn for Bush. Finally, it keeps Cruz in the Senate (warming up a seat for SCotUS maybe).
Sure, some of the Trumpkins will squawk at first but in the end they aren’t going to throw over the Donald just because he picked an establishment running mate.

Thank you (not) for calling me a “Trumpkin,” but, actually, I’d prefer that Trump pick an establishment running mate. I don’t mean a squish (like Jeb!), but someone who’s been in politics and knows the ropes. I think that would help Trump, as President, and help allay the fears of people who might hesitate to support a ticket with two complete outsiders on it.
You might be right about Rubio being the guy, as well. Trump has been suspiciously nice to him (except for his occasional barbs about the guy sweating like a pig).
