My wife tipped to the routine. Nasty was cueing the Dems when and what to do. They got there marching orders to not show their asses. They watched Nasty to know what to do. My wife is never wrong, she told me so.
Believe me....your wife is right!! :-)
I saw hand motions in at least three places, mostly one-handed. The most obvious was when she waved both hands for them to stand up and applaud themselves. They had already done so, but maybe it made her feel as though she were still in charge.
Groupthink in action.
Observant and smart wife!
