In post #587 of the “How can Donald Trump win at this point?” thread I quoted this from one of the protest organizers:
We just feel really strongly that we have to send the message that … we deserve better than to choose between the lesser of two evils every election; to have things to actually vote for, not just voting because they’re not the other guy.
So they aren’t necessarily voting for Trump as bobot mentioned. They just don’t see much difference between the two parties stance on the situation in Gaza. And it appears to me that no, they don’t see Harris doing them a solid, as you say.
