The big story still is the mailed ballot fraud.
Yes, mail in ballots are an issue in certain states like Nevada where the race is close.
This is why we have an Electoral College. We know Trump will lose in CA, HI, RI, VT, MA, etc. IF those states have mail in voting, who cares except for the Senate/Congressional races.
What is important is mail in voting in Nevada, AZ, NH(we do not), WI, MI, OH, FL, PA and any other swing state.
