Even if Trump's legal team has hard evidence and can prove that the election was stolen, and even if they can prove it in court... Don't assume that a judge will reverse the decision.
A reminder that the entire establishment is against Trump and they will keep yapping about "baseless allegations."
Solution: This is where Trump supporters must step in and go out in massive numbers protesting in the street (without rioting). In MASSIVE numbers, not small groups of people here and there. You need to keep up the pressure and do it every weekend at least...
You need to constantly call and and email your representatives and whoever in position of authority. Don't do it once in a big wave, even if their mailbox is full. They delete their mailbox, so you have to keep the pressure, and not make it a one time thing.
Don't rely only on the legal team and their evidence only. They are going against the establishment. They'll need your support to put strong pressure...
My 2 cents.
