8 years as VP makes one too much of a yes man. Pence should take himself out and run on his own against whoever is VP in a 2nd Trump term. He/she should be a successful governor who has served in congress. Brownback may be too tarnished. Kasich/Sanford? Gag me. Jindal(squirrel head). Perhaps he can settle for Walker(Floyd R. Turbo). Problem is he’ll only get in if Trump resigns half way into his 2nd term.
Jindal is ineligible, born to two Indian nationals.
The rest you mention are all Cheap Labor Express Republicans.
