Kinda neat, a bit weasely in a few places. Our Lords and Masters stance has always been Palestinian sovereignty under a two state, but usually they vote against or abstain from any UN resolution iirc.

Hard to know. Maybe it's a tactical move in preparation for the next federal election. Seeing the Dems get obliterated after supporting Israel's slaughter for the past year might have given them food for thought.
