This is correct. The reason "Palestine" took off on the left was that it was a rare wedge issue in which the left part of the Democratic coalition had a distinctively different position than the Biden adminstration's, so it was a convenient organizing tool.

The purpose of the Palestine movement was A) to seize power from the establishment wing of the Democratic party, and B) to reduce the influence of Jews in the American left. It failed badly at the first, but succeeded at the second.
