See my comment on the other thread here about King. King stays in congress because, like Trump, he really does represent the bigotry of his supporters. King's district here in Iowa is mostly made up of western Iowa, which, trust me as a lifelong resident of Iowa, is just as conservative as Nebraska, its neighbor to the west. A state (Nebraska) in which its congressional delegation continued to support Nixon all the way to his impeachment. These people are not rational or very smart. They are all white, religious, very conservative and have never had a personal relationship with anyone different from that. So they keep voting for King.
