Democrats decided genocide is more important than winning elections. Also, the ethnic cleansing of all Palastinians from Gaza was always what everyone in Israel and the US governments wanted. We will see if Trump's stated intention to do more intervention gives enough of a push to meaningfully accelerate this process. The break with the Democrats is just admitting this out loud, rather than some vague discussion of "two state solution" ignoring that Israel would never allow that, and that would require the US at some point turning against Israel.
