There's no evidence anywhere that he intended this as a troll job, but if he did, he's trolling everyone, not just the left. And most people don't like to be trolled.
So...what's the goal of this? To cause even more people to eyeroll him? How does this possiy benefit his 2024 campaign?
Maybe he intends for someone else to be the R nominee and this is part of a plan to basically serve as a diversion?
