“Conservative” Jewry is far MORE Conservative than you claim. You’re thinking about REFORM !
The Conservative movement has been allowing gay rabbis and gay civil unions for 11 years now. That caused a split among the rabbis, but AFAIK this has not been reversed.
Maybe among your particular circle. In general, "Conservative" Jews remain overwhelmingly Democrat.
In the post-election vote breakdown:
The breakdown of Jewish votes between Clinton and Trump was in line with an exit poll published earlier in the day by The New York Times. GBA conducted both a national survey and a survey of Jewish voters in the battleground state of Florida. The national survey results were based on responses of 731 self-identified Jewish voters, with a 3.6 percent margin of error. The Florida survey results were based on responses of 500 self-identified Jews with a 4.4 percent margin of error.Non-Orthodox Jews supported Clinton at higher rates than Orthodox Jews, but the Democratic candidate came out ahead even in this sub-group. According to the poll, 76 percent of Reform Jews voted for Clinton, as opposed to 21 percent for Trump; 71 percent of Conservative Jews voted for Clinton, as opposed to 25 percent for Trump; and 56 percent of Orthodox Jews voted for Clinton, as opposed to 39 percent for Trump. Among those who identified as merely “just Jewish,” 67 percent voted for Clinton, as opposed to 26 percent for Trump.
