2020 could be the next 2008: Dems ride the momentum of a big midterm win against an unpopular GOP president, add the presidential cycle youth turnout for a second consecutive wave election, taking the White House just as the economy craters, completely bogging down the new administration and leading to a wipeout in 2022 as people start freaking out about the "deficit" again. Only this time there aren't enough Senate seats to pass anything and whatever you get through there is knocked down by the Supreme Court 6-3 cause RBG croaked.
