what do you think publicly repudiating Israel would do for the democrats’ chances of winning the presidential election?

Would probably improve them. Dramatically so if backed by actions such as stopping all weapons shipments

It makes sense for them to say nothing publicly while privately trying to tie down those loose cannons.

First of all, no. It doesn’t make sense to publicly do the opposite of what a majority of the population, including an overwhelming majority of your own base, wants.

Also, “loose cannons” must be a new fucking record for downplaying 75 years of apartheid rule and an ongoing genocide!

I dunno… Supposedly British naval tradition is “monstrous! Nothing but rum, sodomy, prayer, and the lash!”* and Trump is a teetotaler who would never pray to anything but a flattering AI rendering of himself…
