Trump's will be a spectacle. Because it will truly be a "bOTH siDes" thing. There will be celebrations and dancing on the grave by anti-Trumpers and probably just relief by normal people. Then on the other side, there will be the wild conspiracies, there will be genuine eulogies that are so positive and promotional of Trump that they seem like mockery/satire to the normal person. Then the more normal conservatives who don't necessarily like Trump, who will be further turned off by the lib reaction.
Biden's will resemble a much more traditional reaction. Sure, there will be some classless celebration from MAGA land, but MAGA is much more widely dispersed, will anyone notice that a couple MAGAs fired their guns into the air in bumfvck Iowa in celebration? But it won't be anything like the joyous reaction to Trump's death.
Best case scenario is Trump loses soundly in November, and then dies naturally of the least controversially way possible shortly after. That would hopefully allow the GOP to move on from Trump as a loser, a dead person, without conspiracy, without having the hoopla of additional trials, etc.
