Stolen might be too strong of a word. There are many questions especially in MI/WI/PA. There was at least the appearance of fraudulent voting. In most cases I've not heard explanations that would give comfort that it was legit. On top of that you have deadlines changed and methods of voting changed by governors/courts when the state legislatures are the only ones with the ability to make such changes. However, after all is said and done, there was not a majority in any state legislature that put up a challenge. Since the state legislatures ultimately have the authority in deciding who the winner is-they are in the end the final say on who the "winner" is.
