Reagan wasn't or at least didn't appear to be an antisemite, Carter was really helpful to Israel in the Camp David negotiations but took a really hard line against the 1978 invasion of Lebanon and settlements in the West Bank (properly, in my opinion, at least on the settlements, but that's beside the point), and Nixon's antisemitism wasn't known and didn't affect his policies, and though he was dirty, and murderous abroad, he wasn't the kind of extremist Republican we have today nor in the Goldwater wing of the party. I doubt there are enough Jews who will support a fascist in the U.S., but we'll see.
It’s certainly possible given the polarization that has taken place since the Gaza war. McGovern, Mondale and Carter got less than that.
It will definitely be a political science case study for academia after the election
