In Florida, which Mr Trump retained, the AP survey put Jewish support for him as high as 41 per cent and 58 per cent for Mr Biden.
The Republican Jewish Coalition said that Jewish voters were “moving Republican” and speculated that the J-Street poll had not included enough Orthodox voters, among whom support for Mr Trump is higher.
But Haile Soifer, executive director of the Jewish Democratic Council, disputed the findings, telling the Times of Israel, “There’s no question that Jewish voters turned out overwhelmingly for Joe Biden last night and it may be the reason he’s going to win,” she said.
With votes still being counted in a number of states, the news channel CNN puts Mr Biden ahead with 253 electoral college votes to Mr Trump’s 213. The winner will need a minimum of 270.
