Thank you. In this case the "cancer on the presidency" is the president.
( Numbers show around 80% of Jews do not vote Republican and also do not support Trump. The 20% mostly come from the Orthodox, which doesn't mean they should be discounted, but many of them are really one issue voters. The greatest concentration of Orthodox Jews in the US is New York City. Regardless of that the entire city rejected Trump in 2016 because they knew him all too well.)
