Concession is not a requirement to losing a legitimate or in this case an illegitimate election. There will be no undoing of the election. We have to pressure our Legislators to separate federal and State election rules and ballots. See my post "we must pressure our Republican Legislatures". Democrat governors can veto State election laws passed by Republican Legislatures but they can't veto the federal rules passed because the Constitution gives the Legislatures the power to set the federal election regulations and those don't require governors signature.
