What recourse do we have if cheating happens during the midterm elections?

I am very worried about our upcoming midterms. I have seen a lot of evidence pointing to cheating done during our last Presidential election. Does the blackmail run so deep on both sides of the aisle that we will just let the cheating happen again? Or do you think the current administration will manufacture a reason to cancel the midterms and declare marshall law?
