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.
Zionism is a desire to have a majority-jewish state that is strong enough to protect jews from future pogroms. It is not a quest for a homogenous state.
And before you declare that the existence of Arab municipalities make Israel an apartheid state, all Israeli cities are mixed.
Likewise, there are Jewish villages. Few of these have Arab inhabitants, but it is not forbidden for them to move in.
