Unfamiliar with it being called “Jew Deal”? OK. History’s not everybody’s strong suit.
How about Roosevelt’s “Brain Trust”? Or the “Gold Dust Twins”?
Ben Cohen was a prominent figure in the American Zionist Movement as well.
At the time, Jew saw themselves as supplicants (for lack of a better term) rather than equal participants. That attitude actually persists today in organizations like American Agudath Israel.
Both names were concocted by media, and were not official groups as such. The "Brain Trust" was a select group of presidential advisors from academia, just about all of them from Ivy League universities. It turns out that your guy Ben Cohen, a law professor, was considered by many to be one of the "Brain Trust," though not in the original group. He is about the only one of these influential academics who was Jewish; most of them definitely were not. That correlates with the fact that Jews in academia back then were rather unusual because of discrimination and immigration patterns (a good percentage of the Jewish population consisted of relatively recent immigrants).
Ben Cohen was also one of the "Gold Dust Twins." The other was not Jewish. Haven't the faintest idea as to why they were given that name, since their policies certainly didn't get the country out of the Great Depression soon enough.
