Because it was so close, no autopsy. Just even more doubling down and claims of a stolen election. You wouldn't even see the tearful journal articles assessing how the American psyche got so broken as to elect Trump, just straight-up assertions en masse of an illegitimate presidency (like what Republicans are doing now but without the whole violent occupation of the capitol, kidnapping governors thing).
Yeah, you’d probably see McCcarthyesque investigations into the Green Party, on the plus side fewer idiotic “let’s talk to Trump voters at a diner in Ohio” pieces.
...And a whole lot of this especially. Everyone who opposes the Democrat establishment would be part of some conspiracy between Trump and a designated enemy foreign country of the week. There may not have been a Congresswoman AOC or a second Sanders campaign.
