Alas, the Guardian’s analysis is merely hysterical TDS as expected; and moreover, the result of the election is not now known—not just yet...
It is somewhat hysterical, yes. But Trump is undeniably a (thankfully metaphorical) loose cannon, and Trumpism a loose canon, with nothing of substance beneath the aggressive and populist soundbites. His past record suggests that his response to an election defeat is to never acknowledge the defeat, rile up the base, and then direct the angry mob at his opponents. Fraud! Lock him/her/them up! Stand back and stand by! Standing by, sir!
America is an abomination, the very worst “evil empire” in all of recorded or recoverable history.
It is the greatest in extent, because it is the empire of the modern age, and has the tools of the modern age at its disposal, and has learned well from the imperfections of previous empires. The system has matured and has been refined. Beneath that, though, people are people. People running an empire are people running an empire. I doubt that people running previous empires were any less perfidious, grasping and self-serving than those running America right now.
Trump is of course not really running America—he's a tool (both common and slang)—but he's carved a route to power that is unprecedented in America, and Republicans and those shadowy figures behind the scenes* will be willing to an extent to indulge him. Trump may be a lame duck, but Trumpism is alive and (probably) kicking. He knows that he personally is on the way out. Expect the last couple of months to be concentrated essence-of-Trump (now there's a stocking-filler for Christmas). The question really is how loose his leash will be.

Why are they always shadowy? Surely they'd be more effective if completely invisible?
