There actually isn't that much denial by conservatives/pro-Trump people that I've seen. No one is really coming up with convoluted ways the results could ackshually change after the fact, certainly no one is rioting. Conservatives pretty much say "welp this is a fucking bummer" and resume their lives because it's not a huge surprise (the mainstream media had 4 whole years to hammer TDS into people after all). As soon as the Democrats started pushing for people to vote by mail (because voting in person is unsafe) I think most of us knew perfectly well what was up, and predicted that mail trucks full of just enough "misplaced" Biden ballots to get an edge in swing states were going to suddenly be found around 4 or 5 am. Trump's presidency was kind of a pressure release valve for people who were sick of the establishment, but his refusal to toe the line meant they were going to throw everything they had at him (the dumbest impeachment ever, saying supposed drug use and later the coof made him medically incompetent, sexual assault accusations, tax fraud accusations, etc) and I know I sure as shit didn't expect they'd stop short of straight up dead ass cheating.
This is a long shot but it would be the funniest thing ever if it comes out that the Democrats colluded with Russian hackers to fuck with the election
