commented this elsewhere, but the general idea is that by showing that an important contingent of the left won’t vote for a pro genocide president, the democrats will have no choice but to run a candidate that is electable in the future.
this means that trump might be president in 2024. That sucks, but most of the damage has already been done (supreme court, senate, etc). Might as well show the dems that they have to run a candidate that supports the rights of civilians all around the globe
As a game dev who’s making a better game with worse graphics - i think people who say this are in the minority, unfortunately.
