Do not trust Thiel.
In the words of a smart person on another site:
“Thiel is the owner of Palantir, part-owner of Facebook, and part of some other shady companies. He talks MAGA, but he lives and breathes among the far left, giving them massive financial support. He also endorsed and financed John McCain, Carly Fiorina, and Mitt Romney. I doubt his challenger funding is actually intended to succeed; it’s a PR stunt, for the gullible who will go, “Oooh, MAGA!” without actually looking at his history. This may indicate he’s planning another foray into politics.”
Thanks for that info.
