Going so outside the law and normal order has consequences: At some point in there, random disconnected people start burning down Senator's and Rep's home offices, threatening them or their families, or actually taking pot shots at Congressmen. Being a Republican Congressman who won't act against Trump becomes dangerous. Their jobs are not just in jeopardy, their lives are at risk. The Secret Service becomes over-burdened trying to provide security for every Congressman and his family, his home office, his residence, and so on.

I think under those conditions, enough would decide Pence is a perfectly good option.

Please note that I would never do any of these things. I'm just saying that there are millions of people out there who would support it, and thousands who are crazy enough to do it. We've already seen it at that Republican softball game.
