They aren't going to rise to power as a grievance party without blaming Germany's WWI defeat and the economic crises on somebody, who will that plausibly be?
As socialists, yet not of the Marxist orthodoxy, the ITTL NSDAP would be more than happy to blame incompetent generalship, the industrialist class for war profiteering, and the nobility as the bloated bourgeoisie who betrayed the working class and peasantry to try and preserve their station.
As for their Jewish policy, they would certainly excoriate Jewish Communists and the KPD as a foreign, degenerative influence, however when it comes to Jewish WW1 veterans and Orthodox Jews, they would be praised for their loyalty to the Fatherland, and they would be encouraged to purge the Bolsheviks and money-manipulators from their community.
This timeline is basically what would have happened if Hitler had died in the Beer Hall Putsch and Strasser had become the leader after and the NSDAP had had help from a Jewish Freikorps in the uprising.
Jewish FK leader after the Putsch to Strasser: "For you, the loss of 12,000 soldiers on the Western Front is a statistic, but for us it is a national tragedy, and one made meaningless and nearly honorless by the traitors and Communists in both of our nations." (Strasser's anti-semitism was founded on his economic beliefs and his left-wing politics much more than any eugenic/racial component.)
