Conventional wisdom re: picking a running mate to deliver a state seldom works (see: Ryan, 2012).
But he is a long-time Senator who will get some deference from colleagues, he’s a good spare in case something happens to Trump, he’s conservative enough to discourage the GOPe trying to do Trump in, and he’d help to shore up the conservative base in not seeing Trump as having gone all sell-out for moderate votes by the time November roles around.
Reminded another show had a former McCain campaign guest who is now supporting the Libertarian say Trump can’t possibly win New York and California and Republicans shouldn’t waste resources there, what a quitter, no wonder his candidates lost, and now he’ll be happy at 10% voting libertarian...
I’m with Trump, run the table!
