Remember, Trump himself has yet to get the very same jab that he pushed so hard to bring to fruition. That right there tells me all I need to know. I believe the theory is that if he'd fought against it, the DS could have taken as long as they'd wanted to develop it, and keep people under covid tyranny the whole time. At which point, they could mandate it b/c it would have been FDA approved (approval process takes quite a long time), and that Trump doing what he did was making the best out of a lose-lose situation and saving face in the process.
