But Jews are separate from all other nations, by definition. This separation is similar to that between the holy and the secular and Shabbat from the rest of the week and is mentioned as such in the havdalah prayer.
`Am Yisra'el is a Theocratic nation in exile and until the "enlightenment" was actually an autocephalous religious community. And things were probably better back then (there were no "branches," for one thing).
True, HaShem through the Prophets and Sages instructed Jews to be loyal to their lands of exile and to pray for them. But Jews are first and foremost the ancient Jewish Theocratic polity in exile, and that must never be forgotten. The fact that it has been is why Judaism has been turned into a mere "religion" with liberal "denominations."
Not disagreeing with you, however the Jews Michelle is speaking of on the left wouldn't accept that premise, factual or not, and won't be swayed in a secular election by that approach.
