I'd argued as the election was called in early November that the Turd was spent
I thought this would be apparent sooner rather than later, though as @Isaac Ji Kuo pointed out, settling the Georgia Senate run-offd, thanks to Stacey Abrams, was the decisive turn. I learned of yesterday's coup attempt tuning in to catch election returns, and finding myself occupied somewhat longer than expected.
That said, my assessment seems to have held up well; Trump is spent and it's gone quite poorly for the GOP.
See previousdly: Spent.
