I don't know how or why politics has become a social media shitshooting contest but even at that level of immaturity, Biden still has more substance to his posts than Trump. So, to me it's very simple, both candidates are becoming immature and #voteme #otherguyiscorrupt #yoloswag though Biden seems to do this in a more in-depth and sophisticated manner with actual reasoning behind his social media jabs. Trump just shitposts and loves doing it, his post length alone should make that obvious.
Thus, I do not understand either side making this about 'the other side is a tantrum thrower' this is about more than that, you need to analyse the regime they stand for and how they're going about things. Trump is corrupt to the core and has been completely pro-establishment his entire time as President, despite his promise to be a rebellious lover of the working American. You can think what you want, it's just a fact. He's handled Covid so terribly that the US is the only fully developed country that is having an upswing of cases, all other highly developed countries that US would call its equal or inferior, are on downswing pretty much.
