I think that's only part of it. Yes, Evangelicals are big into supporting Israel, but there is also a fact that the Israeli Right-Wing are quickly becoming political enemies of the Globalist Left. Israel's theocratic right-wing is not co-operating with the Leftist factions, and is seeking to damage them at an institutional level, while the Leftists try every trick in the book to keep the right from power (even through judicial corruption and fake movements).

"Pandering to jews and christians" is un-nuanced. Currently, there are a slew of progressive christians that are in favor of Drag Queen Story Hour and Black Jesus (See the Anglican Church), and the Pope is a Liberation Theologist.

We need to talk about which jews and christians. Trump supports the Nettenyahu right-wing coalition, which have a hard emphasis on making sure Israel exists for the benefit of religious jews. The Democrats get lots of support from progressive American and European jews & financiers that are more philosophically based in Zionism (a secular, progressive, nationalist, jewish state) that would be fucking purged from Israel if they were forced to adhere to jewish religious doctrine; even to the point of losing their citizenship.
