So far, the GOP has had a good Gaza war. The right, with a few notable antisemitic exceptions, has been united in favor of Israel’s right to bounce the rubble; the left, on the other hand, is divided, mostly along generational lines. For the left, Gaza is a wedge issue, just as abortion is for the right. It represents a problem that needs to be fixed before the 2024 election.
And in time, it probably will be. Biden embraced the Israeli cause as long as it revolved around getting rid of Hamas, but the focus of the struggle is about to change to what happens next. Every indication we have suggests that Bibi sees an indefinite occupation as the least worst alternative. Biden isn’t going to agree with that, and his rhetoric about political initiatives is going to sound more and more pro-Palestinian. That will help unite the left, while the right will continue talking about bouncing the rubble and ignoring Arab opinion during the campaign.
In short, the generational issue on the left won’t go away, but it should be possible to put a patch on it.
