I don't believe the election was fair at all, it's illegitimate. But there's no question as to who's president.
I reject AG Barr's premise that trump lost because 10's, may hundred's of thousands of voters cast straight, party line ballots, with the exception of abstaining from voting for Trump. Investigations are still being held, people are being arrested for voting violations. Finally, there is no rebuttal opportunity on this sham committee, no representation from opposing views. Much info is being withheld that we should know. If/when there's a red wave, a real investigation might take place. These monkeys are too deranged to offer rational cases.
