The "Shoe on Other Foot" and "What Goes Around" Arguments in Politics

Political nearsightedness is running rampant in our America of recent years, and at no time has it been more on display than in the last few months.  It seems that the overwhelming majority of politicians in Washington speak and act as if their ruling side will be in power forever and that any election or piece of legislation has catastrophic, world-ending consequences if it doesn't completely go their way...and of course the "other side" is run by corrupt extremists.  People-at-large have their own legitimate political orientations, and they usually subscribe to either the conservative, Republican camp or the liberals, with the Democrats as their group.  It would help all of us, regardless of what we want to see done...or not done...in Washington, to realize that the two parties go back and forth between being in power or in opposition every few years or so.  Losing a round of elections isn't the end of the world...unless you're talking about an authoritarian, ultra-narcissistic sore loser like Donald Trump, who has still refused to concede the 2020 election to the winner, Joe Biden.  On January 6th some two thirds of the Republican House representatives rose up in opposition to officially counting the Pennsylvania presidential election results, which Biden won fair and square.  That's far beyond a simple show of protest and portends a future in which possibly a party holding majority power in Congress can undo a national election that the other party's candidate won...and it could happen as soon as 2025 if the Republicans win back the White House in a close contest and the Democrats still run the House and Senate.  It would help if each of us stood back and took the long view on things, considering what it would be like if the shoe instead were on the other foot and it was the Democrats objecting to a free and fair result last November that handed Trump reelection.  Precedent is a very big thing in politics and the Republican grandstanding over the 2020 election is a very bad one.  Other bad precedents that ignore the "shoe on the other foot" and "what goes around comes around" principles have been the removal in the United States Senate of 60-vote thresholds to advance and confirm presidents' nominations, the Democrats starting it in 2014 and the Republicans extending it to Supreme Court nominees in 2017.  Now talk is about for the Democrats to end the legislative filibuster, something that Republican Leader Mitch McConnell resisted doing while Trump was president and his party controlled the Senate.  I say keep things the way they are...what good is it to pass a bunch of controversial bills on 51-vote majorities and then have them automatically reversed when the other party gets into power as soon as 2-4 years later?  Better to work on and achieve compromises on legislation between the two sides that will stand for years, something the Democrats are sadly skirting with this COVID relief bill they are currently forcing through by means of a convoluted legislative process called budget reconciliation, and something that the Republicans tried when they attempted a few years ago to end Obamacare (failed) and pushed a huge tax reform bill (passed).  The notion of packing the Supreme Court by adding four new seats to give the more liberal wing 7-6 majority status is another bad, bad idea doomed to backfire.  Again, what goes around comes around...
