Unfortunately, that isn't likely to happen. Netanyahu has, to date, handled Trump deftly and Rubio's current presence in Israel seems to be aimed at offering support to the ground offensive, not opposition. I honestly have no idea what kind of backlash it would take to shake U.S. support for this genocide.
It is worth noting that Andrew Cuomo, in a desperate last-minute gamble to boost support in the NYC mayoral race, has come out against Israel. Considering that much of the attacks on Mamdani have focused on his support for Palestine (construing him as antisemitic), it's notable that other candidates also seem to think that being anti-Israel is actually the vote winner for moderates right now.
I understand that that's the current shorthand, but it seems inaccurate and unnecessarily polarizing to me.
Albert Einstein added his name to a famous letter to the NY Times in the late 40's, in which EXACTLY THIS was explained, in plain & uncompromising language, in the very first paragraph. For Israel to exist, it would have to be just like the Nazis. That's LITERALLY what that letter said.
The splitting of a non-existing hair argument that you're trying to do is just to avoid admitting that you've been wrong the entire time, and enough people warned (or boasted) about it from the very beginning that you really don't have an excuse for being this wrong.
