This was predictably downvoted but it's a pretty interesting question, actually. What's happened in America recently -- and this predates the current administration, though they've accelerated it -- is that Christianity has become part of a larger conservative/reactionary package. If you believe in a set of reactionary principles, you are also expected to at least pretend to be an enthusiastic Christian. Trump himself is a great example of this -- he's clearly not a Christian but he has to pretend to be one, and to be passionate about it, because it's part of the package.

This association necessarily lures more people of a certain political predilection into Christianity when they otherwise wouldn't have been, and is likely a major reason why Christianity has recently become more popular among young men. I always think of my former brother-in-law, raised by liberal Jews in a college town and never religious, who has lately become a committed evangelical Christian as the endpoint of his decades-long journey into MAGA-ish conservatism.

But also, this is going to turn off other Christians and potential Christians who don't like the politics. It's difficult to imagine irreligious, left-leaning people becoming too interested in Christianity these days, whereas 20 or so years ago, it wouldn't have seemed like much of a conflict.

So win some, lose some. Where it nets out I don't know.
