A lot of the leftie reaction to all this shows how little the average person actually knows about the political processes that govern their country. The fuckin votes don't get cast until December, and the hand-off doesn't actually start until 2021. People are acting like because Biden 'won', Trump has to immediately leave the White House and abdicate his presidency. The way that Biden is chest pounding about how he's going to force Trump out is retarded.
Since the votes don't happen until December, why wouldn't you fight tooth and nail until then? You're not slowing up any of the processes, and if a race is this close you owe it to your voting base.
