At 70, and with a list of endorsements from centrist Democrats, including Hillary Clinton, Latimer is far from the exciting prospect Bowman was four years ago. He is, however, a vocal advocate for Israel – in the final debate between the pair he declined to criticize Israel, something Biden has previously done – who visited the country before launching his campaign against Bowman in December. He has won the support of Aipac, and was endorsed by the Jewish Democratic Council of America in March.

Much of the money has been spent on attacking Bowman. The UDP has invested $14.5m in the race – $9.8m of which has gone towards knocking Bowman, and just $4.8m on promoting Latimer.

If Bowman is defeated, there is a potential impact beyond just politics in the Middle East. Some younger, progressive Democrats feel that the primary campaigns against Bowman and other Squad members could drive young voters away from the Democratic party.
