They didn't win by a landslide, huge numbers of minorities voted for Trump, they are going to have to cheat even moreso in the coming months to have a chance to potentially steal the Senate (and even then, only have a 50/50 tie with Kamala as the tie-breaking vote), and while they held the House, the GOP made massive gains to cut Nancy's majority down to the point that the moderates can now tell AOC and the anti-Semite squad to kill themselves for being a cancer on the face of humanity and threaten to deny Nancy renewal of her position as Speaker, due to the decrease in Nancy's majority in the House being reduced to the degree that the moderates no longer have to eat shit and can force Nancy to can the SJW crap. And basically reduce uppity cunt supreme AOC to such a degree of tears that she's now threatening to ragequit her House seat because the moderates no longer have to cow to her and her anti-Jewish mean girls cliche.
As such, Trumpism is not going away and barring Trump being arrested by NY State prosecutors and "accidentally" sent to Gitmo instead of NY Federal lock-up, Trump is going to be kingmaker and a continued thorn in the side of the DNC/left. Especially since the lunatic left so blatantly stole the election in a way that will ensure the next four years, the GOP will be rallying around Biden/Harris's tenure as P/VP being illegitimate and the threat of Trump running in 2024 or worse, a spiritual successor who will be Trump minus all of the morality or restraint due to said successor seeing how Trump was done wrong by everyone and who will behave/governor with ZERO restraint towards crushing their enemies on account that Trump showed mercy and was stabbed in the back for showing such mercy.
Even the media can't hide this; while they are cheering Biden/Harris on like they are, they are also tacitly admitting that the Democrats fucked up on all elections down ballot and that this is going to handicap the Biden administration SEVERELY when they get sworn in. Especially if the Supreme Court crushes Biden's ability to rule by executive order fiat via the recent ruling they used against Trump saying that you can't undo an executive order of a previous president just because you don't agree with it on a moral level. And double especially since Kavanuagh, Bennett, and ESPECIALLY Thomas, all fucking have legit vendetta level hate boners towards Biden and Harris, meaning that the Supreme Court's probably going to actively FUCK BIDEN AND HARRIS TO DEATH to avenge past wrongs Biden and Harris did to 1/3rd of the Supreme Court.
