It will work because the "Governor" is doing this so late in the game. AND, he runs the office that would have to comply with a court order countermanding his decision. Which means there will be "unexpected delays".
Something we all have to keep in mind, there is no mechanism - NONE WHATSOEVER - for "redoing" the election, even if rampant and deplorable voter suppression/intimidation is found to have happened. And the team on the side of our better angels can only play defense. The GOtrumP can go on offense and disrupt and dismay up and until/after the day of the election, and the results will stand.
