Illiberal left ideology has its greatest strength on campuses because campuses are one of the few places in American life where a certain kind of far-left politics can actually impose hegemony on other ideas and really control the discourse in a way it can't in most places in American life where even moderate liberals are more of a minority.

Because many people remembered a time when the Republican Party was not so extreme, and hadn't full grasped how much it had changed, people blamed Obama for his failure to get Republicans to agree with him. That blame coloured so much of how the public saw Obama during his presidency. The public thought he was dealing with a brand of Republican leader that just didn't exist any more.
