Which points should we cede? Banning gay marriage? Banning abortion? Banning any sex education that isn't abstinence-only? Banning women from running for President because 1 Timothy 2:12? Abandoning environmental and sustainability policies because the end times are near? Roundfiling the 1st Amendment? No, I don't think those are things worth doing.
How about devolving decisions about placing the ten commandments in classrooms to local authorities? Pretty low consequence stuff, particularly if it will just get struck down by the Supreme Court. It's lousy posturing, but that's nothing unfamiliar in politics..
Or just finding a charismatic (in either sense) religious Democrat from the middle of the country to run.
Colin Quinn's conceit notwithstanding, Trump's appeal to evangelicals (which is what we really mean when we talk about "Christians" in an American political context) was neither a surprise nor a mystery to anybody paying attention. I hear "How can Christians vote for Trump?" as less a genuine expression of bafflement than a rhetorical question intended to call out the hypocrisy of those who profess moral values that their favorite candidate manifestly does *not* embody.
Sure, but accusations of hypocrisy also fail to understand MAGA for what it is: a grievance movement against what they perceive as condescending liberal elites.
And I don't agree that this is just about appeal to evangelicals. The perception of liberals as being contemptuous towards religion is broader than that, and extends well into the "spiritual, but not religious" crowd. I've had plenty of (non-evangelical) religious people ask me "But don't you think there's something greater than us?" and there's just no good answer to that question. If I say "No" I'm arrogant, if I ask "What exactly do you mean?" I get "You know what I mean." If I say anything else I'm dissembling. When I google "woke atheism", one of the first hits is this quote: "People that call themselves atheists subscribe to the religion of woke." That's not from Pastor Steve down at the First Church of Christ on a Cracker, it's from Joe Rogan, someone I don't think of as overtly religious at all. Sure, he's an idiot, but he does seem to have tapped into something.
You mention elsewhere that Democrats tried to ape Trump's trade policies in 2020 and it got them nothing. Ceding anything significant to evangelicals will most likely yield Democrats even less.
I'm not suggesting that it would work, or that Democrats ought to do it. We're never going to have the kind of empirical support where we can say "
This will work." This is mostly Lucy and the football stuff as far as I can tell. We have South Park centrists who told us Trump and Biden were equally bad, because Trump is a goon and Biden is in cognitive freefall. When Biden dropped out, did they say "Great, clear improvement, now I know who to vote for"? No, because "both sides bad" is just an article of faith for that crowd. They just find different reasons why Harris is equally bad. You mentioned that voters are liars; I think it's worse than that. One of the most enduring insights from the behavioral sciences--most of the time, people don't really understand what is motivating them.
I'm just pointing out that among the "cultural issues (like transgenderism)" that some Americans see as tainting the Democratic brand is a perceived lack of religiosity. The next congress will have one more openly trans representative than it has open atheists. And few here are likely to advise Democrats to strive to be seen as friendlier towards religion, because few here particularly want them to be.
