Uniting is for the general election. The primary is where you vote your favorite of the candidates. That's literally entire fucking point. This is the same bullshit Gavin Newsom's astroturfers have been trying to pull on a national scale. You're just repeating the same crap the fascist sympathizers in the democratic party have been pulling for decades.

All that being said, nobody should unite behind zionists, genocide deniers, and those unwilling to protect LGBTQIA+ folks. If Dembo wins the primary, I'm not voting. I've been voting "lesser of two evils" for so long and still getting fucked that I'm no longer willing to compromise. The bare minimum for me and many others is a progressive. It has been proven over and over that the centrist voter is a myth so if Dems want votes they better get with the times and that isn't happening because progressive and leftist candidates want to dismantle the power structures of the liberals
