They’re part of a wide community that saw a bunch of messaging about how “I will NEVER vote for Kamala Harris because (reason), I just feel like (thought-terminating cliche)”, and got suckered by it. It happened that the reason was “Palestine” and the thought-terminating cliche was, “genocide is a red line for me” or one of the other flavors. I think you’re right that the Palestine audience was pretty small, but the total of all the audiences was absolutely massive. I think that was what cost Harris the election. They just know how to do manipulation of the public on a whole new level.

The messaging was even often contradictory depending on the audience being spoken to. She enabled a genocide, and she betrayed Israel, and she’s soft on crime and crime is everywhere, and she’s a cop who locked up black men for possession of a joint, and she’s even more cruel than Trump on immigration, and she wants to wreck our country with open borders, and she ruined the economy.

Only a tiny fraction of it was ever true, but if you’re the target audience for some piece of it, and got exposed to the messaging every day, it starts to sink in. It’ll resonate with you.

The one thing that’s darkly comic about this whole situation is that Netanyahu hasn’t yet realized what a terrible partner Trump is for anything. He’s going to rush into a full-scale war with Iran, and then ask Trump to be sending all the aircraft carriers and weapons and doing all the agonized diplomacy Biden has been doing for him that always shields him from consequences, basically try to guilt trip the US into winning the war for him. And someday, instead of doing that, Trump’s going to say, “I tried but they wanted me to put it in writing or something, I don’t know, this is hard” and stop returning his calls.
