One could make similar statements (and some do), about voting for the democrats over a better farther-left party. The defenders of voting Democrat would likely tell you the same thing: “Its our only chance at winning.”
Are you voting for genocide if you compromise and vote for the Democrats? Or are you merely making the best of a broken system?
You decide.
People have proposed multiple reasons why the Democrats lost. This is one. Them “continuing to play gender politics” is another.
A simple “They kept supporting isreal + they lost = they lost because of supporting isreal” lacks evidence. I believe this is rather complex.
