Antisemitism won over rival movements by letting parties attack the state through the Jews

Evidence

The fact that similar formations without active antisemitism—which avoided the charlatan aspect of the antisemitic parties and therefore seemed at first to have far better chances for final victory—were finally submerged or liquidated by the antisemitic movement is a good index to the importance of the issue. The antisemites’ belief that their claim to exclusive rule was no more than what the Jews had in fact achieved, gave them the advantage of a domestic program, and conditions were such that one had to enter the arena of social struggle in order to win political power. They could pretend to fight the Jews exactly as the workers were fighting the bourgeoisie. Their advantage was that by attacking the Jews, who were believed to be the secret power behind governments, they could openly attack the state itself, whereas the imperialist groups, with their mild and secondary antipathy against Jews, never found the connection with the important social struggles of the times. — Hannah Arendt, The Origins of Totalitarianism, 152
