For those younguns who say, "I wasn't even born yet" as an excuse for ignorance, let's talk Congress and President. The pols may claim they are bipartisan or above it all (that's a good compagin ploy) but the memories of their parties' shames are too powerful to ignore and too painful to forget or to forgive.
Since the election of Barack Obama as POTUS, we've seen this at its worst. For you millennials, let's talk Nixon. The disgraced GOP Prez lives on after his rehabilitation and then his physical death. Even though he skated free form jail and removal from office by the grace of his VP, Republicans know he was the pits and he got caught.
Big deal, you scoff? This is what happened with Presidents Clinton and Obama. It's what has been happening in recent years with obstructionist Congress. It's what continues to divide neighbors and families as well as legislators. We'll see more of it.
I'll rant about turning tides and swinging pendula.
