I seriously doubt Trump has interest, aptitude, or temperament to study and learn the details of all the great issues facing us. In addition, I don’t think veeps have very long coat tails. Kasich doesn’t guarantee a Midwest win.
Trump would be getting “talking point details” from those experts on the plane. The experts would be the guys in the administration with the details.
As far as veep coat tails, a guaranteed win in OHIO is YUGE.
Secondly, Kasich would give an air of moderation to the bombastic Trump image. Solidifying his base and winning over fence sitters.
As far as a Trump/Cruz ticket, I just can’t see it happening. With Trump POUNDING Cruz with the eligibility issue, how could he pick him for veep (again Article XII), not to mention the bad blood between them.
