Sadly, I think Pence has a better chance of defeating Biden than Trump does. And it scares me, because I have lived in Indiana under Pence. He actually believes a lot of the things Trump professes. So, in a sense, he has more integrity, but he also has theocratic tendencies that Trump does not.
Pence was raised a Roman Catholic, and later became a born-again Evangelical. I’m not sure what denomination he officially belongs to, but he was a regular church-goer, and at one time proselytizer.
Pence may not be able to rally a “base” like Trump has, because I don’t think he has a cult-type personality, but he does have charismatic appeal-- more than Biden. Personally, he makes me sick, but that’s just me. Anyone who agrees with him is going to like him. Biden, on the other hand, depends on people agreeing with him, because he’s really not terribly likable-- that’s not to say, he’s dislikable, he’s just not someone you want to pal around with, and Pence is, assuming that you even minimally share his viewpoints. I don’t know if I’m expressing that well-- I mean that, people who like Pence love him; people who agree with Biden don’t necessarily like him.
Most people I know who are planning to vote for Biden aren’t really enthusiastic about it. They are either in their minds voting for the Democratic party, or against Trump.
I think that while Pence won’t inspire the cult-like devotion Trump has, facing Biden sets the bar very low. He doesn’t need to be Trump.
HOWEVER, given how unpopular Pence eventually was in Indiana, I think the one saving grace is that he has a good chance of being a one-termer. I think he’ll very much be a George Bush following up on a Ronald Reagan.
