There could be 2 days even before than filled with drama.
Tomorrow: No action by Trump means at midnight tomorrow night parts of the government shut down.
1/3: No action by Trump means that the stimulus package that was passed is pocket vetoed.
If Trump just does nothing, I don't think that there is anything other than invoking the 25th amendment that can be done to either reopen the government or pass any kind of stimulus until Biden is sworn in.
January of next year has a decent shot of being quite dramatic. And this is all on top of the incoming Christmas surge for the virus.
NEVER A DULL MOMENT!
