Easy....Nanzi told us. She stupidly held a gleeful impeachment signing ceremony---handing out pens like she was already in office.
That alone, will go down in history as her biggest blunder.
I read here on FR that in the moments after her tearing up the official SOTU speech copy, she pronounced that Congress was "dissolved". Not adjourned.
It seems in her shattered-dream moment, she couldn't resist play-acting her inner megalomaniac; just as with the passing-out-of-pens episode mentioned, she exposed her inner desire to rid her world of Trump, then Pence, and then upon assuming the Presidency be rid of the current elected Congress by dissolving it, to be reformed with syncophants of her own choosing.
