People asserting Jewish influence in American politics need only quote PM Menachem Begin's first visit with newly-elected President Ronald Reagan in 1981 and Begin's offer to "help out" with some votes in Congress, which was an insult to the integrity of the U.S. Government (and yes, we still believed in it back then). Which is not to say that Israel was any sort of national adversary then or now.
All that said, one doesn't have to stretch at all to see how virulently anti-Semitic the Iranians are, and it should disturb anyone to see the Obama Regime hesitate to call the Iranians out on it, and to worry about the Regime's motives in hesitation.
I think 11 US senators are Jewish. Which is around 6x their percentage of the population.
I don’t have a problem with that, but most Jews are strongly liberal, and liberals are the ones who are constantly bringing up statistical disparities of this type as proof positive of discrimination.
