You don’t know what you are talking about. Jews really turned on Jimmy Carter and helped elect Reagan in 1980. Ironically, they moved back towards Mondale in 1984. . lol.
But Mondale was more pro-Israel than Jimmy Carter was.
Israel wasn't the issue in 1984, but Mondale was supportive. As was, imo, some disagree, Reagan. I wouldn't want to make the case one way or another. But that's not what people were voting on.
