If he loses I dont think he'll cause a fuss, he loves America
But on the other hand, all his enemies (the Left, social media companies and 95% of news networks) have had a reputation of blowing things up and out of proportion during his term. He could let something slip and you wont hear the end of it til the election is officially over.
Even then he wont be off the hook with the history of Presidents blamming stuff on the former guy.
If I were him and I lost, I'd retreat, deal with the issues that have come up (that no one will care about anymore) and kick back on Twitter taking shots at President Harris for bungling up the pandemic even more than he apparently did
he dodges the question whenever he's asked about a peaceful transition of power...that doesn't sound like someone who loves america and doesn't want to cause any problems
