Nation-level gerrymandering

Yes. That was the election Nixon was actively cheating in, given that the Watergate commission was able to trace it right up to the president.

It would totally be nice. That's why it's enshrined in the first amendment that you have the right to petition your representatives for the redress of grievances. Sadly, they do not act on those petitions (Professor Lessig has studies, and crabby calls and letters to your Senator have a net zero effect) which how protests escalate to civil disobedience (to sabotage and eventually civil war).

But it's interesting how quickly police are turning to anti-riot responses, and our government officials are supporting them. It's noted in COIN (counter insurgency) that brutality against protests only increases public sympathy and support for the movement (which has been consistent with incidents in the past decade, the US unrest and protests after the killing of George Floyd in 2020 being a run of examples.) I suspect it's less 4D chess and more like Trump being angry and wishing to assert his authority.

But our officials, the plutocrats they serve and law enforcement all regard the US Public as the enemy, and have been consistent about it since the 9/11 attacks. It's one of the factors that's been driving us towards civil war, or the end of our democratic features and one-party autocracy.
