Schumer was brought into a briefing on Iran and clearly 'got his mind right' in there. I don't know who makes decisions in government, but it's not the people on camera. US elections are irrelevant to consequential matters, and we waste too much time thinking about them.
I think this framing is bad, it's not that people don't think there are consequences it's that it's 50/50 on whether the consequences will be personally worse for them. There are few, maybe no upsides, to elections in the U.S. for the majority of the electorate.
It's not said in polite company, but Israeli concerns are racial, not religious. If you meet a Jewish zionist, then you've also met an athiest. An explanation of Christian Zionism deserves much longer discussion than can be made here, but how and why such an obvious contradiction to Jesus' ministry gained popularity is something worth studying.
Once you realize the gospels and the epistles disagree, it becomes a lot easier to understand. Christianity is the practice of cognitive dissonance. The bible, due to the nature, has a lot of mixed messaging.
Imagine, for example, you wanted to write the religion of Liberalism, so you collect the works of all the major thinkers on the subject of liberalism into one book. Now imagine someone gets the bad idea that all these authors must actually have a unified view on what liberalism is, means, and implies. You'll end up seeing that person teach a form of liberalism that's easily countered with other passages from their book and they'll mostly just wave it away because they have their passages and the others are simply you misinterpreting an "obvious" metaphor.
That is christianity in a nutshell, just replace liberalism with god. That's why there are so many sects. Because it's just too easy to yell "Context context context!" when a difficult passage comes up you don't agree with and use "spiritual" as the excuse for why you don't actually have to follow that passage.
1. Many Israeli Jewish Zionists are either "traditional" (religious but not that much) or Religious Zionist, and they are generally part of the right wing coalition. Actual atheists tend to be in the Israeli (still-Zionist) left.
2. The Zionist conception of Jewish identity is not "racial" in the American sense. The most obvious sense in which this is true is that it considers converts and their descendants full members of the nation. Probably the closest analogies are some Native American nations' identities or Armenian nationalism.
But you're directionally correct - Zionism is not a particularly religious ideology within the Jewish world, and outside of the Religious Zionist minority the political class is (openly!) on the less observant end even on the right.
My totally unsubstantiated conspiracy theory is that several of those are sitting in shipping containers in the US and Europe, and that is part of the reason that their interests drive all western foreign policy, despite their open hostility to their 'allies'.
