Progressive Leaders Warn Biden's Support for Gaza 'Slaughter' Risks Millions of Young Votes

Of course it would be better for Biden's reelection prospects if he could remain popular with both younger, more left-leaning voters and older, more centrist ones, but I think the latter group is bigger, more likely to live in a state that isn't solidly Democratic, and actually willing to vote for Trump. (Trump is, in his not-very-coherent way, probably at least as pro-Israel as Biden.)

With that said, my guess is that Biden is actually doing what he believes is right, rather than simply maximizing his chance of being reelected.
