I don't think the Jews will be contributing to Biden's campaign. They are going to rally behind a different Dem candidate, and it ain't going to be Biden.
Israel is on our team.
They are our # 1 Ally in the Middle East.
They are nuclear power.
They got our back......we their theirs. (& vice versa)
If we war......they war with us against our enemies.
They were Dem in the old days.
And......those days are gone.
