Trump is in favor of giving more power to US corporations and letting money speak ("deals", or bribery depending on your POV).

He's a very good defense against politicians with stronger ideologies, especially those more aligned with international values which tend to smooth out specific cultural gripes.

Despite the down votes I think this is right. The reason the "conservative" side has voted for Trump is more voting against the other side. With maybe a Mitt Romney type and an actual primary, the religious right would go that way. Many conservatives do not like trump, but consider him better than the alternative.

I'm grateful my parents, who were life long conservatives, haven't lived to see the tragedy of what passes for Republicans these days.

You're not wrong, in a vacuum. Proper puritanism would have been disgusted by trump for a good 20 years before his presidency. .

It's too bad that puritanism is often co-opted by the largest hypocrites. SO perhaps they would vote him in in practice.
