I would say let’s start with accountability for politicians in general. It’s pretty common for idiots mess up locally and then self promote upwards to state and federal levels.
Accountability absolutely starts at the top. If we expect to re-establish accountability for rubes first while turning a blind eye to those in power, then we are just playing into their hands.
This is what we are not supposed to talk about. The people outnumber the ruling class, and, operating all the means of production, could wield power by simply going on strike, bringing them to heel long before revolution is necessary.
People won't do it today because they are both comfortable and too chained to their current jobs. They are increasingly divided by culture war bullshit that is not at all relevant to the important parts of society, like accountability for leadership.
Politicians can't just appoint themselves to Congress or state legislatures. You may think they're idiots but citizens are voting for them. Is it possible that some of those "idiots" aren't as stupid as you think but rather just have different priorities and values?
In an ideal world, politicians who don't work on improving the lives of their constituency wouldn't get voted for.
As that is not the case and improving the lives of their constituency doesn't necessarily get them voted for again AND whatever good they did may get undone before it really shows its effects: of course they only care about being reelected... Even if they had ideals and morals to begin with.
Information and investment assymetry means there will always be election-winning rewards for dirty politicking. An actually effective politician, who has morals must balance the two. And they must try to be more skillful in general at politicking than their unscruplous rivals.
This sounds much more like "Please Don't Hold My Politicians Accountable" than "I favor accountability", FWIW.
I know decorum here disfavors talking about specific parties and actors, and this thread is 100% sideways. Nonetheless this kind of attitude is at best only a stepping stone to recovery. You can't both-sides your way through a constitutional crisis.
Not unique to politicians, any large organisation who doesn't have a strong single leader sees this. It's nothing new either, with the Peter principle, the Dilbert Principle, even the Gervais Principle, recognising the symptoms.
Having the authority to sanction a president does not necessarily mean that person has the power to overthrow a president. And the people with the most direct power (military and secret service) lack the authority to use it. Mostly these factors can balance out so that power is not concentrated as much as it seems.
