Even if enough fraud is shown in Michigan, their election laws let the certified vote stand no matter what (which is why they rush to certify the moment they achieve the result they want).
If they think they can’t stop Trump, we should start monitoring House/Senate, governors and AG races because they’ll focus on undermining him and the states that vote him in. Michigan is another great example from 2016: elected Trump at the same time that witch and her bitch won.
