There are also religious people who look forward to the coming of the “end times”. They also vote.

yep, they definitely do

More importantly, US oligarchs are religious. Mostly evangelical, mormon or some postmodern derivative, like Thiel, Yarvin, Musk and their ilk.

In the US, even people who aren't very religious in practice still harbour religious beliefs like the state of Israel being a divine entity. I.e. like Ted Cruz, who knows some english biblical phrases but isn't religious enough to stop himself from playing golf with the pharaoh, and yet strongly holds on to the antisemitic zionist belief that jews must move to the state of Israel and eradicate their neighbours.
