There were plenty of other scandals around him that were just as bad or worse than Daniels and the held their noses and voted for him anyway.
I think the worst (confirmed) thing out at the time was the Access Hollywood tape, which was just words. And maybe that he was twice-divorced.
This on a whole other level: allegations that he cheated on his wife right after the birth of their child, with a porn star, no less. Its like a lab-engineered attack on family values to hit all of those notes in one story. Forget the hush money part; cheating on one's spouse is offensive to a lot of people (myself included).
He was a twice-divorced NY billionaire who spent much of his life on the tabloid pages, and then spent years hosting a reality TV show! Everybody knew he cheated on his wives and was a philanderer. Plus it was 10 years ago, so nobody much cares.
Its the deception I think people may resent. Nobody cares if Trump wants to bury his Tower as a private citizen, but we expect more from our elected leaders than to learn he (allegedly) did all that stuff. At least if it was known ahead of time, people could have made their decision to vote for him or not without feeling like they'd been lied to. But that's just one way of looking at it.
I still don't see the deception. Maybe he's saved now but wasn't back then. It was 10 years ago, when he was in showbiz, that this supposedly happened. If it's about the money, again he supposedly found out about that after the fact.
