Again, showing my age, but in high school in the 90s, history books tended to go up until Bush I and the fall of the Soviet Empire.
Most history classes used the Civil war as the dividing point semester-wise. Fall semester was Jamestown/Puritans through either start of the Civil War or end of the Civil War and Spring Semester started with the Civil War or Reconstruction and usually got as far as Watergate/Reagan getting elected if we were lucky and didn't miss any school due to snow.
Also, the left has been systematically burying the draft dodging parts of the left in regards to Vietnam. It's one of those things that they realized was bad PR for them in rewriting the narrative of Vietnam and it gets super glossed over these days if it gets mentioned.
Also, I would not be shocked if one of the reasons the Lincoln Project exists is to explicitly ensure Trump becomes a villain for all times. Neocons will NEVER EVER allow another Trump to happen again, since he basically shattered the entire ecosystem going populist that ensured the Neocons stayed in power. Ironically, the religious right basically caved to the reality of Trump for the sake of the courts and a seat at the table, even if it's the kids table.
The Neocons are just DYING to do their own purge of Trump supporters, from the GOP party and base and if it destroys their ability to get re-elected again, then so be it. Hell, I would not be shocked if the LP folks haven't already extracted promises from Biden, shit that will give him the leverage to tell the lunatic left to fuck off by having the Neocons/LP folks agree to help Biden in various projects in exchange for no court packing and other "gifts" to the right to preserve the status quo for the neocons. At least until they fully regain their strength and stab the Democrats in the back.
