it'd also be good to mention that there exists a strong, largely right-wing and evangelical, pro-Israeli lobby in the US that make it politically very costly to not demonstrate unequivocal support
Look at abortion for example, do right wing evangelicals value this issue less than their support for a 10-thousand+-kilometer-away country? did they manage to make it controversial and costly to not adopt their position on it?
Right wing evangelicals do performatively praise Israel more often, but actual lobbying is strongly bipartisan and cuts across the conservative-progressive divide.
Being anti-abortion is a political litmus test in many parts of the US.
Contrast that with majorities that pro-Israel laws always get in congress. Trump even recently complained outright that "Israel used to control the congress" and he didn't even mean it in a bad way, the ADL shat its pants and quickly tore into him saying that it's AntiSemitic (^TM) to say that. Nobody in the Democrats is willing to approach criticising Israel with an INT_MAX foot pole except possibly old-school anti-imperialism marxists, and they are fringe.
