Trump's coup attempt is bound for Coup Total Landscaping. He's so far behind electorally that he has to corrupt too many people in a coordinated way at once. Collective action problems prevent Evil from overthrowing democracy, so Good will win.
His big plan, I think, is to rope Republicans into his nonsense. Many will play along with the idea that he was robbed or say the outcome is uncertain until the Electoral College makes things official. At that point many GOP primary voters will be permanently convinced. That gives him a nice power base for the next few years.
Trump's one true business skill is winning a bankruptcy. He had six in his hotel and casino businesses. He walks away with most of what's left, leaving customers, creditors, and clients to curse their deals with the devil. We'll see how many Republicans end up in his hell.
