Theory (Credit goes to someone else)
Checkmate.
Trump is daring them to enter the fence to finish the coup. They must all know there is a chance that if they enter the gates and go inside the fence they may never come out.
Even better is they literally made a prison complex out of Capitol Hill in front of everyone's eyes and the left and MSM cheered them on!
Is this why Biden pushed his rehearsal? Are they debating whether Trump is bluffing? They have to decide - go inside the fence line and risk never coming out or concede and try to make a deal.
CHECKMATE.
You want the Presidency?... COME AND GET IT!
For all intent and purpose, Trump has made DC the foreign territory it is and walled it off - just like the border.
Trump will be President of the US under our original constitution. Biden, if even inaugurated, will be president of bankrupt DC - an entity that has no control over the rest of the US (even though they convinced us it did.)
If true, it's a brilliant move - basically scraps the entire DC cesspool.
