F6 linked that one to - Matrix999, Why Christian conservatives supported Trump — and why they might regret it
[...]
Well, now you put your finger on the real heart of my book. The case I’m making is that he ended up with a highly visible sales team full of religious leaders who supported him. All of the other GOP candidates were more authentic, more articulate, and had deeper evangelical roots than Trump. But Trump wisely started meeting with clergy to hear their concerns. He wisely became a champion of opposition to the Johnson Amendment. He came out strongly against abortion. He came out strongly for religious liberty.
That then won over prominent clergymen like Franklin Graham and James Dobson. They became apologists for him and used language like, "Well, he's like Churchill. Maybe profane but still ordained.” One of the big positions was that he's Cyrus the Great from the Old Testament, where Cyrus was a vile pagan but still used by God for his purposes. All of this was bandied about. All of this was spoken from pulpits. All of this was said on religious media and secular media like Fox News, etc.
So the answer to your question is the religious conservatives were convinced by their leaders.
They felt Obama and Clinton had them under siege. Trump was Machiavellian enough to say all the right things to their leaders. They believed Trump's lie that the Bible was his favorite book, and that he was gift from God. https://investorshub.advfn.com/boards/read_msg.aspx?message_id=139581179
