Your logic undermines the President's arguments that the state courts modifying mail-in voting statutes for the selection of Electors is unconstitutional.

In PA’s case, statutes were rammed through in defiance of the PA Constitution.
In GA’s case, election laws were changed in defiance of GA law.
And so on.
In each case, the issues have not been adjudicated. The respective courts have dismissed or contrived inappropriate principles, laches in the case of PA.
