The uncommitted vote is an easy way to tally how many care enough to protest vote. In Michigan, where the messaging beyond the anti-genocide sphere was strongest (this movement has little money), almost 20% of the vote was “uncommitted”. That’s a significant portion of the Democrat base that cares enough to protest vote against genocide! Keep in mind there’s plenty of Democrats who oppose the genocide but wanted to show support for Biden as a whole. Support for ending the genocide is significant, and while the news orgs continually downplay it, for a large amount of voting Democrats it is clearly a priority to end the US-funded-and-supplied genocide of a people who literally cannot escape or be protected in any way.

And do not equate “supporting Israel” with “ending the genocide”. Israel have extensive strike capabilities and defensive capabilities including the Iron Dome, the Palestinians get entire housing units imploded in the blink of an eye. If the US did everything it could to force Israel to stop the genocide now, Israel as a country will continue to exist. If the US does not stop the genocide, the Palestinian people in Gaza will not continue to exist. When Israel attacks the bottom quarter of Gaza that is still standing yet holds almost all of the Palestinian people, the civilian casualties will be enormous since they’ve all been penned in there (hence this is termed a genocide).

You are correct on the general voting topic. All people, regardless of party affiliation, with any critical thinking skills are aware that Biden will be better than fascist Trump (for Gaza “complete the mission” and the US #insurrection) and come general will vote for Biden. I understand some want to “make him sweat” but that must be done in other protest venues as in the general it’s a binary choice between Biden and fascist-who-is-worse-on-literally-everything. So I am confident the vast majority of Democrats who voted uncommitted in the primary as a protest will vote Biden in the general, as any alternative does not make logical sense.
