O.k. I never weigh in here but this will be the 1 exception. Despite having impeachment, an election, and a pandemic in 2020 this is actually going to be the pivotal moment of the year because short of some R restraint and waiting until after the votes are counted and a Biden landslide in the election and a change in control in the Senate (which BTW will send the Rs into an internal civil war because Trump ain't going no where), there's no way this ends well for the country.
The origins of this date back to the progressive moment at the beginning of the century which envisioned a more modern, more progressive government. Even with Wilson they weren't able to get the job done until the Great Depression and FDR's new deal which expanded federal power way beyond that envisioned by the founders. The Supreme Court pushed back, FDR threatened to pack the court, and in Wickard the Rs backed down. The Rs having been routed in the depression elections didn't have the will to push back, there was some wishful thinking that it wouldn't be a long term or big expansion, and then WWII and the Cold War hit and some Rs rallied around the idea a modern expansionist government (and imperial president) were necessary to stop international threats. There were also the monied interest in the R party (those white shoe Republicans) that were happy with the post war economic expansion and didn't want to rock the boat if it threatened their monied interest. The Ds meanwhile were also undergoing a change from a party that tolerated segregation to one more rooted in ideological constructs. The Great Society pushed government modernization even more forward, but Roe was what broke the back. It pushed all the evangelicals into the R camp, with the end of segregation there was no longer a reason for a certain southern element to continue to support the Ds, and it convinced ideaological conservatives there was no limit to the Ds expansionist read of the Constitution. The Supreme Court thus became the end all be all of the fight, because it had the ability to interpret/rewrite (depending on your point of view) the Constitution, and all without the usual amendment process.
Then came the start of the political Cold War: the Bork confirmation (which you'll Biden of all people played a key role in). The selection of judicial nominees was now politicized. Rs played this game of trying to get political appointees through that weren't overtly political (such as Souter) but it came back and bite them later). On the R end, Goldwater and then Reagan were the first political pusb backs in favor of a more limited government, But R voters, especially with the end of the Cold War, got increasingly tired of interventionist foreign policies and foreign wars. R voters also increasingly began to turn against the elites and in more of a populist direction for economic reasons, and then also got tired of the Rs trying to fight like gentlement when the Ds were prepared to do what it took to win like in the Bork confirmations. IMHO there's actually a political realignment occuring with middle class AA and Hispanics moving to Trump, older Americans (in part due to him letting the pandemic "happen") moving away.
Clinton tried moderation. George Bush tried "compassionate conservativity". But then came Obama (who particularly irked Rs by strawmaning them and often painting them as unreasonable and irrational if they disagreed with him) and the Rs and their refusal to cooperate even from day 1. The Rs accelerated things with the M Garland stunt. The Ds with their fillibuster nuke. Obama tore down some norms by resorting to executive orders instead of going through an increasingly disfunctional Congress. Congressmen on both sides were shot. The '16 R primary was an existential fight between the populists and the old pro-interventionist establishment wings of the R party. Trump won largely due to frustration by the base with the "gentlemen" who wanted to negotiate-- even Romney got villified by the media which was increasingly showing itself to be partisan-- they wanted someone who would fight and tear it all down. Kavanaugh, impeachment, pandemic, riots. Kavanaugh especially has broken the nomination process.
So here we are with a Congress which no longer functions, an executive which is ruling by fiat, a pandemic where the fight is between how broad federal and local powers should be and how broadly citizen's rights should be infringed, political violence which threatens stability, and a Supreme Court which both sides now view as the essential key to governing in light of Congress not being able to accomplish anything. So here's what we could be looking at now: the Rs win in a tight election and the Ds go insane and burn it down claiming cheating, the Rs push this through by a razor thin vote (with Murkowski and maybe others not voting) maybe even with the VP and the Ds win and respond by packing the court, the Ds win in a tightly contested election and the Rs go nuts claiming the election was stolen, there are disputes and a 4-4 court is unable to decide them. Short of an overwhelming Biden win and the Ds taking the Senate, which will destroy the R party, the country is so f-ed. I'm increasingly convinced at this point if not outright civil war, there is no way we escape widescale political violence. My 2 cents. I'm outy of here...it's chilly,.
