Eh. "A Majority of Voters" is not that impressive. According to Gallup's running poll, Democratic Party affiliation is currently at 28%. A slim majority of a minority is... nice? It needs to be reflected strongly among independents and perhaps the opposite party to be reflected in the general population. For comparison, the majority of Republicans think the 2020 election was stolen. This view is not reflected among the general population.

I actually think a more notable statistic in this poll is the Republicans at 23%. That tells me that reactions to what is happening in Gaza has had a bipartisan effect, which has often not been the case with Israel.
