I hadn’t heard about the sexual assault allegations, but I’m not really surprised. What I have heard is that “The People’s Party” is technically not even a political party (and thus doesn’t qualify for ballot access), and that “leftist” “comedian” Jimmy Dore is a prominent member. The fact that West even considered working with them makes me question both his judgement, and his seriousness as a candidate.
There were plenty of other factors that may have pushed Trump over the line, and most of them come down to Hillary being a bad candidate.
