Liberals beg for the obfuscation of power through democratic politics.
Trump strips that away to reveal politics as pure will to power. Which shows radicals that all power comes from the barrel of a gun, as Mao said. Which must be good for the world if power under capitalism is seen more clearly for what it is: as the ruthless competition between members of the ruling class for control of the rest of us, the enslaved populations of the planet.
Trump is gauche, but Biden shows that Democrats are just as willing to shut down the border and engage in genocide and brutally crack down on protesters and vote for an unqualified candidate. It might be useful for Biden to be in power to radicalize people away from electoralism entirely. He's taking the mask off the Democratic Party.
its true that radical movmements tend to grow under second terms of democratic presidents in recent times. (see obama and clinton)
