You want to destroy Joe Biden? After he leaves office, he is powerless in the Democratic Party. What is your plan to make the Democratic Party less pro-Israel? Tell us!
The reality is that Jewish Americans have always been more civic minded than the average American.
Many Jews consider Israel to be their "spare country". If there are pogroms in the US, UK, France, Canada r wherever, they will always be welcome in Eretz Israel. So they are mre prone to be single issue voters, and Israel (including its domination of the whole of Palisrael) their single issue.
A much larger percentage of Jews vote. It is also true that Jews are wealthier than most Americans and some are spectacularly wealthy, and elections are expensive.
There are the facts. I think they are indisputable. Now, tell us, how does the Democratic Party advocate ceasing arms to Israel?
