According to this latest NBC News poll, 67 percent of Democrats say that their sympathies lie with Palestinians over Israelis. This is an astonishing sea change in the opinion of a major part of the electorate. Just thirteen years ago, in 2013, only 18 percent of Democrats said that their sympathies lay with the Palestinians.

This shift, moreover, is not confined to Democrats. Thirty-seven percent of independents claim that their sympathies lie with the Palestinians; only 27 percent claim that their sympathies lie with the Israelis. In 2013, those numbers were nearly reversed: 37 percent of independent voters claimed that their sympathies lay with the Israelis, while only 10 percent of independent voters claimed that their sympathies lay with the Palestinians.

As NBC goes on to report, this stark turn in the Democratic electorate is now driving a series of Democratic primary contests in congressional races across the country. There’s little doubt that it will also shape the 2028 presidential primary.
