Would a white evangelical Democrat have any trouble winning the Dem nomination?

It would most likely be a non-issue. As long as an American politician from either party is some flavor of Christian, it's pretty much a non-issue these days, aside from maybe a few places in the South, well, and Utah, but it's very much a special case.

Pretty much. Clinton was a Southern Baptist, and that was almost never mentioned or remarked upon. It would be even less of an issue now.

Clinton wasn't a convert, like in my scenario.

BRTD, when you say evangelical, what kind do you mean? Are they a Clinton style evangelical or more of a religious left candidate?

Think a pretty standard Democrat that just happens to be an evangelical. Closer to religious left then I guess.

Considering how many Americans change their religion at some point during their lives, I can't see even that making much of a difference.
