(CNN) President Donald Trump claims that Jewish Americans, who are traditionally staunch supporters of the Democratic Party, are leaving it. A look at the polling data finds, however, that Jewish Americans continue overwhelmingly to be Democrats and opposed to Trump.

Jewish Americans voted for the Democratic Party by about a 3:1 margin in the 2018 midterm elections. This was true whether you looked at the exit poll data , a large pre-election study of Jewish Americans for the non-partisan American Jewish Committee conducted by SSRS (who conducts CNN's national polls) or other non-partisan studies . Other polls for partisan organizations with large sample sizes also back up these findings. In the exit poll, Jewish voters backed the Democratic candidate for Congress by a 79% to 17% margin.

Jewish Americans are far more likely to call themselves Democrats than Republicans. In the 2018 exit poll, 64% of Jewish voters identified as Democrats compared to only 10% who called themselves Republican. The SSRS pre-election poll put the Democratic identification advantage among Jewish Americans at a slightly less impressive but still quite large 51% to 16%. The rest of the voters either identified as either independent or not with any party.

Further, when it comes to party identification, Jewish Americans are just as Democratic as they were before Trump became president. In the 2016 SSRS poll, 51% of Jewish Americans were Democrats compared to 18% who were Republicans. That's the same percentage who were Democrats in 2018, while Republicans actually saw a 2-point drop.

Polls indicate Jewish Americans aren't fans of Trump. The 2018 exit poll, Gallup in 2017 and SSRS in 2018 all put his approval or favorable rating at 26% or lower among Jewish Americans. His disapproval and unfavorable rating among Jewish Americans is north of 70%, while his strongly disapprove or strongly unfavorable is higher than 60%.
