I don't believe this is specifically pro-Trump or anti-Biden, it's the pressure cooker of decades of frustration over continual growth in government intrusion into private lives that needs to vent.
In a sense, this is even better than just a Trump reelection, it's individuals saying "Thanks, but no thanks." to "the system".
It would be even better if an election was held and noone showed up but instead just turned it all off ... except I know personally that it can be a tough habit to break.
