Perhaps it's just me, but what I know about what makes a religion (and what I know seems unable to unmake it) suggests that the devotion to Donald Trump (not to a party, not to a platform, not to an ideology) constitutes a religion. As I think all personality cults do.
Some observations:
All Christians routinely ignore some horrifying stories from the Bible, and yet accept them as part of their devotions.
All MAGAs routinely ignore many horrifying stories about Trump, yet accept him as the focus of their devotions.
The vast majority of senior Trump supporters were implacably opposed to him at first, ran against him claiming he was so wrong for the party -- and then wound up supporting him, often completely contradicting their previous positions in the process.
The vast majority of Christ's supporters were originally the Romans and other polytheists of the ancient world. Those who Jesus arose from (Jews) reject him as "divine" even today.
