It’s possible that his views were conflicted.
I have family whose politics I understand pretty well, and I don’t know who they voted for. What I do know is that they were torn between: “Trump’s blatant antisemitism is a danger to us here in America” and “Trump is good for Israel”.
As far as I’m concerned they’re there the same reason; ethnonationalism is a coherent ideology. But explaining that to them is not going to get me anywhere.
