This guy is fucked in the head and his daughter is probably fucked in the head too. I'm going to give her a pass, thanks.'
Here's another interpretation of his behavior:
1. He's a narcissist (iow, he's in love with himself).
2. He sees his most attractive daughter as a reflection of that self, as a sort of female version or side of him.
3. He isn't perving so much as showing that he can't resist himself. So even though it's a social taboo to behave that way, he's so attracted to his own reflection that he can't help but act like he wants it. He might never act out that self-love beyond a certain point (i.e., he probably never tries to actually fuck his daughter), but he doesn't want to fuck her, Ivanka, the person, so much as he wants to fuck the bit of himself he sees in her.
I'm not on expert in this area and I'm just talking out my ass, but I'm pretty sure my theory is a lot closer to the truth than yours.
