Yeah, that's great and all, except all of it exists solely in your head. It's a fantasy. He got mollywhopped by Biden among the "Nones" in 2020. They actually supported Biden far more robustly than Clinton. He was actually less popular with this group than any Republican candidate in 20 years.
Among White Americans, worship service attendance remains highly correlated with presidential vote choice.

He's not bringing over anyone areligious over because they are more attracted to his feigned Christianity and pro-Christian policies. Independent breakaways have nothing to do with that. It's because the core Republican voters are becoming less religious. They care about adhering to marriage less. They care about "traditional" marriage less (i.e. gay marriage). They care about prohibiting abortion less. They care about nuclear families less. They care about charity and volunteerism less. They care about maintaining a strong and well-funded Church less; a church that, while separate from the state, maintains a check on the state's power as an institutional lobby. In fact,
they increasingly believe the Church should not play a role in helping to mold policy. All of these classic positons associated with religious belief, specifically Christian belief, are eroding, and that is showing up even among those who identify as Republican.
So, everything you just said is wrong. But otherwise, yeah, sure. Spot on analysis. Not a deluded fanboyist take.
