The 2020 election steal was an attack on the United States. The attacking forces won and took over the government.
No different than if a physical army marched in and took over the government.
Going back to WWll, as an example, what good would it have done if the courts in France or Holland had declared the Nazi takeover illegal? Or, if the legislatures in those countries had voted that the Nazis must leave?
This is where we are.
Loyalists, for whatever reason, are not ready to or able to take back the government at this time.
Occupying government gets to run the day to day. If the citizens are in no danger, the loyalists won't take action. It's entirely possible that the citizens accept the occupying government. That's why, IMO, Bidan and the misses keep saying how great everything is now that they have "healed" America, after 4 years of the pol elite and the MSM blowing smoke up everyone's ass criticizing anything that Trump did. Malice of forethought. It was planned.
Deciding factor will be if the citizens decide, for whatever reason, to not accept the occupying government. That's the main battle front at his point, and why Trump is not letting the issue die. Americans can't just rollover.
