Would you demand Donald remain POTUS if somehow it turned out that the Democrats really did cheat? I'm not saying they did or that it will ever be proven. I just have a suspicion that a lot of left wingers wouldn't care enough to do the honest thing even if it was true. Getting rid of Trump matters too much to them for that to ever happen I think.
It's a fair question and I think most normal people would say he should remain president.
But just to give you an inkling of the type of person - in Trump and large number of con whackadoodles on this site - you are dealing with.
You could have 1000 Dem voters who have all their ID on them, prove where they were born, the day, the time everything - and actually have Republican scrutineers watch them vote, and Trump and his acolytes would say they were dead people. Or they were not real. Or they were illegal aliens.
Yes, they are that far gone...
