The mistake is to talk about "America's Jews". There are Orthodox and Conservative Jews, and then there are (mostly Leftist) Reform Jews, who while ethnicly Jewish, really worship Socialism more than they respect Torah
The Leftist Jews-in-name-only will support the Democrat Party as long as it advances socialism. Too late will they discover that, once Muslims gain important influence, that the Saudis' money will buy control of the party away from them
When DemocRATS start referring to them as "Cosmopolitans" and expelling them from the party, it may finally cause an awakening.
The Golden Calf.
