This isn't going to happen because of the growth of the alt-right. Anyone Jewish will be slandered to the point of ruin.
The Antifa left doesn't like Jewish Americans either.
Um, wrong. The "antifa left" dislikes pro-Israel politicians, whether they are Jewish or not. Left wing opposition to Israel has nothing to do with anti Semitism, unlike on the right.
When a movement believes that a political opinion held by the vast majority of Jews is grounds for violence against members of that group, that is de facto anti-semitism.
The antifa movement is aligned with the massively anti-semitic BDS movement and their tendency towards indiscriminate violence makes them a massive threat to the Jewish population, especially the centrist liberal majority.
I find it unlikely there'll be a Jewish president in the near future. Not enough conservative Jews, and the Dems are only going to become less friendly.
