As I’ve been saying only for a bizillion years, there is no Israel Lobby:
And because the deal stands, one hoary old myth should fall: that of the “Israel Lobby”, and its supposed secret, malign control over the U.S. government. The Israeli state and major U.S. pro-Israel organizations were foursquare against the deal. Yet, not only did they not defeat it, but they couldn’t even get a bill of rejection to the President’s desk.
The only useful thing about the myth is that it masked just how much Israel is a project of the US. But to believe that there is an actual influence that some sort of an Israel Lobby can have on the US politics, one has got to be all shades of dense.

I think that the votes of most of the Jewish legislators on the Iran deal had more to do with party loyalty than their religion (which backs up the argument that to so-called “Jewish lobby” isn’t a force to be reckoned with).
Since Eric Cantor resigned after losing his primary run, there isn’t a single Jewish Republican in the Senate or the House.
