Pence was put on the ticket to lock down the evangelical vote, but inso doing, Pence himself has traded away the moral high-ground. My guess is that he did it to get Gorsuch and Kavangaugh and (hopefully) lock the court up as very conservative for another 20 years.
Wonder if he'll think it was worth it on his deathbed, forever remembered as Trump's biggest supporter and defender.
I think he knows what he is getting into and he is fine with it.
He is probably praying that the president would do something that would cause him to get impeached, and he can be the president.
Could be. However, historically speaking, vice presidents have not fared very well getting to be President. Of those that made the jump from VP to Pres have rarely enjoyed two terms. Ironically, Nixon seems to high-water mark for VPs (in a manner of speaking)
List of modern VPs that did not become President: Barkley, Humphrey, Agnew, Rockefeller, Mondale, Quayle, Gore, Cheney, Biden...
List of VPs that served just 1 term: Ford†, Bush Sr., Johnson*
List of VPs that served more than one termp as President: Nixon**
† Ford was never elected President, nor elected VP. He lost the only Presidential race he participated in to Carter.
* elected one term plus served out 1 year after JFK was assasinated
** Of all the VPs in the last half-century, only Nixon was elected twice (then resigned in disgrace).
Of those 13 listed above, only Cheney never ran for President. Biden ran in '08 but not after serving as VP.
