They are arguing that all mail in voting and early voting is unconstitutional because Congress set a fixed day for elections to be held.
I don’t think their argument is going to fly.
THey are arguing as to how the laws were changed, thus making the ballots illegal
No... “The common maxim, delegata potestas non potest delegari means that powers which have been delegated to one branch of government cannot be re-delegated to
another branch. This is especially true when the United States Constitution has specifically delegated a power to state legislatures, as in this case the plenary power
to direct the manner of choosing electors. But in this case, executive officials in Pennsylvania, Georgia, Michigan, and Wisconsin usurped these powers without the
Legislature’s consent.”
Each state’s House and Senate must make those changes or allowances.
The Executive branch of each state cannot unilaterally do that.
