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.
The contradictions are sharp enough that no one can keep the "US democracy" glamour from further unraveling, and those same contradictions have appointed the most ghoulish and farcical as its "frontrunners" again. They wouldn't be sitting where they are if they weren't both perfectly suited to lead the death march.
But the liberals who want to see the glamour will continue to see it, no matter how much gunfire demonstrates the real flow of power.
didn't move them, and 
hasn't either.
