The poll found 50% of Democrats approve of how Biden has navigated the conflict while 46% disapprove — and the two groups diverge substantially in their views of U.S. support for Israel. Biden’s support on the issue among Democrats is down slightly from August, as an AP-NORC poll conducted then found that 57% of Democrats approved of his handling of the conflict and 40% disapproved.
It depends on how you define progressive, but largely I agree not much else could have reasonably been done, regardless of how progressive they are.
But Biden’s situation is unique to him and his campaign. A Bernie incumbent wouldn’t be needing to defend his progressive alignments and policies, but Biden is very much fighting an optics battle. He is pitching himself as “the most progressive president in a generation” because his survival depends on that demographic. Whatever your opinion is on what he’s actually done, his polling numbers clearly indicate that the progressive base does not believe he is sufficiently progressive. This conflict fucks his messaging, and the progressive caucus seems fairly animated by this issue particularly.
Again, it would be pretty hard for him to loose reelection (though I would strongly caution against assuming so), but that doesn’t mean he can’t still be put way on his back foot for his second term.
