If the Insurrection Act was intended to guarantee constitutionally-protected rights, as any plain reading of the Act would demonstrate, then I can think of no greater application than the right to vote.

Whenever the President considers that unlawful obstructions, combinations, or assemblages, or rebellion against the authority of the United States, make it impracticable to enforce the laws of the United States in any State by the ordinary course of judicial proceedings, he may call into Federal service such of the militia of any State, and use such of the armed forces, as he considers necessary to enforce those laws or to suppress the rebellion.

It wouldn't be a stretch to say the actions (and inaction) taken by Democrats and their co-conspirators in this election usurp the will and rights of the People and defy federal law to the extent that they constitute an open rebellion.

This sounds like a slam dunk.
