Mike Pence would be wise indeed to consider the plight of Sarah Palin.
Regardless what is thought of her now, at the time she was far more presidential. And certainly for more conservative. And correctly so in my way of thinking, because John McCain should never have been considered for the position. As he has proven many times since, he is no conservative.

Pence  more conservative then Donell Trump, but then again who isn’t? Certainly, Pence was brought on board to ththroa sop at the wing of the party that Donald Trump has almost exclusively been centered on alienating.
Add to that  idea that Mike Pence has just signed on for at least a year and possibly five years of apologizing for the utterances of Donald Trump. I don’t know if that’s a job I’d wish on anybody.
And finally consider the idea that when the buyer’s remorse over Donald Trump gets to full volume which win or lose it will do, Mike Pence will have at that point ended any political aspirations whatsoever.
Personally, if I were in his position I’d be backing out right now.
