There's also this though:
^ - There were no reliable polls immediately after the election. The usual sources — the National Election Pool and the Associated Press — did not post Jewish voting results. Partisan polls came up with results that, predictably, reflected their biases. The left-wing J Street exit poll, for example, found that Jews favored Biden 77%-21% while a Republican Jewish Coalition poll showed Biden winning the Jewish vote by a narrower margin – 601%-31%. The more neutral American Jewish Committee survey was not an exit poll. It showed that 76% of Jews supported Biden. “Findings of the 2020 AJC Survey of American Jewish Opinion: Presidential Politics,” AJC, (October 19, 2020). We are using the Associated Press VoteCast survey conducted by the nonpartisan National Opinion Research Center. AP decided not to conduct an exit poll because so many people now vote without going to a polling place. The NORC survey was conducted between October 26 and November 3, concluding as polls closed on Election Day.
And Biden won the national vote closer to 51-47, not 51-49.
