There were many little things during the day that's will inevitably come back to us if not already mentioned by keen eyed observers.
But the one little thing I observed was Bill Clinton and Bush, neither of whom looked in any way pleased that pressure on them has been released. Both looked like they knew they were sitting through another set-up/illusion/hoax. Playing their part but only in their physical presence, which in a sense they couldn't avoid. They were trapped by the narrative now around them. Had they not appeared, they would have been seen as not endorsing the legitimacy of Biden by diehard Democrats (unforgivable) or rumours of them being under White Hat duress would have circulated in Trumponian circles.
So they were trapped and had to show up. But their hearts weren't in it. Which would be strange considering a guy like Biden should be seen as their saviour from all the pressures going on in the background - IF he was really President.
