(JTA) — President Donald Trump’s approval rating among Jews in the United States is 31 percent.

That is more than 11 percent lower than the president’s overall approval rating of 42 percent, according to a Gallup poll taken from Jan. 20, the day Trump was sworn in, to March 15. (On Monday, Gallup’s daily tracking put Trump’s approval rating at 37  percent.)

Gallup points out that Jews appear to be reacting to Trump along party lines. Some 64 percent of Jews identify with or lean toward the Democratic Party, according to data from the same time period, and 29 percent identify with or lean toward the Republican Party.

Gallup also points out that Trump has sent “mixed signals to American Jews about their position in the country and his administration’s stance toward Israel.” Among the issues was his administration’s perceived delay in denouncing a pronounced wave of anti-Semitism and failing to mention Jews in the administration’s International Holocaust Remembrance Day statement. The president also appointed a pro-settlements ambassador to Israel but then calling on Israel to “hold off” on building in settlements.

Trump has a “significant opportunity to boost his image among Jews, Americans and the world,” Gallup reports.”During the campaign, Trump talked about using his negotiating skills, and those of [his Jewish son-in-law Jared] Kushner, to reach a peace deal between the Israelis and Palestinians. If Trump accomplishes what his predecessors could not by negotiating a peace deal, this could certainly affect his approval rating not only among American Jews but among all national adults.”

Trump’s approval rating among all those polleed is lower than any other president at this point in his first term since 1945, when Gallup first started conducting the survey.
