I don't know all the details, but it seems to me like this is why anyone supporting #palestine should fight like hell for #rankedchoicevoting
If we had #rcv right now, I don't think the DNC candidate (whoever that was) would be able to ignore Palestine. The #DNC itself would not be able to ignore it.
So that's why I think #Democrats (at least their leadership) will fight to oppose RCV if it ever becomes a real possibility. They absolutely do not want to be forced to weigh the needs of their constituents against the needs of their wealthiest donors.
