In my view your idea is consent to the two party system, which is not explicitly forced by the constitution, but is being enforced more and more over time by your own behavior. One needs to have limits at least on what they consent to, even when their choice is neglect afterwards. The fact that not even both parties offered a pro zionist candidate, but even inside the democrat party, both candidates (Biden then Harris) were explicitly pro Zionist, this shows where loyalty to an institution no matter what leads to.
Christianity is often ridiculed for for being fanatic, but even though it is a religion, it had reforms (Martin Luther and the protestant denomination eventually) when the main Catholic church was corrupt (I'm sorry for the Christians reading this if I'm getting history wrong). My point is: this was a religion and accepted reforms, here we're merely talking about a political party, a progressive one if I'm not wrong.
