I am ALL FOR IT if it is done in the courts... I think that overturning obvious ballot-stuffing is great. And I think inconsistencies (like not allowing Republican observers) has to hurt. But proving widespread ballot tampering had better come with incontrovertible evidence... And in that case where it is down to a last gasp, I would far prefer the mulligan to state legislators assigning electors.
You forget the other half that will not believe you, and you are doing to them precisely what you think they are doing to you. By and large, it is not the American people who are acting in bad faith, Democrat or Republican... It is the political machines that are acting badly. To overturn the American people is a profoundly bad mistake.
Unless you want war.
You and I know that won't happen, it will be Biden in the White House. But it will be a Pyrrhic Victory, that is tainted. And he will not be a popular President.
Trump is doing this because it keeps the base with him. If he had conceded too early, he would have lost a good chunk of them. Now, he gets to fight another day. Yes, he may temporarily lose some people who think he's taking this too far. But when they see the disaster of the Biden/Harris administration, that will be forgotten.
Note that since the election, Trump's approval has actually gone up, not down. America will have a serious case of "Buyer's Remorse" next year.
