I'm far less concerned about emboldened supporters than I am about the likely backlash by the state. Events like this are always taken as justification for more harsh oppression of the people. Also, Biden now has to make statements sympathetic to Trump. This couldn't have gone worse - we get the blowback from an attempt, and he's able to ride this to more popularity.

Assassination isn't the way, folks. I know you're hurting, I know you're disempowered by the electoral system, but Trump and Biden aren't the core of the problem. You can't cut the head off because it's not a snake, it's a hydra. The way to beat this system is to build alternatives and wean people off of their dependence on it, and deprive it of victims. You have to starve the beast.
