Much evidence suggests successful politicians get offered free sex by women who want to add a famous scalp to their coup stick. Why can't guys like Clinton and Cuomo just take what's offered and stop hitting on the ones who don't offer?
I suppose the offers encourage the pol to imagine he is the proverbial "God's gift to women," a babe magnet. Therefore, women not offering sex are viewed incorrectly as playing hard to get.
That is a guess, I've never been any sort of politician, successful or otherwise. While I've known profs who claim to have been offered sex for a grade, it never happened to me. Perhaps because I never acted like the grade was negotiable.
