The election could have been overturned legally. But “The Courts” rely on the other branches of government to actually enforce their rulings.

With the proverbial, Or in some cases literal, guns of the Legislative and Executive. The Judicial branch and Supreme Court are in essence a bunch of people in fancy robes arguing about crap the majority of the population either doesn’t care about, or can’t follow, because the argument is in legalese as opposed to plain English.

And at the moment. Neither the Legislative and Executive seem inclined to actually enforce any proposed ruling in such a case.
