Question: has the South Carolina State Election Commission so certified Ted Cruz?
If so, then file a cause of action against the South Carolina State Election Commission challenging their certification of Ted Cruz.
See how far you get.
BTW, this is in a state court; my comments have been directed toward FEDERAL court procedures.
No. But that doesn't matter because the suit would be against the political party. If you read the statutory reference, you can easily see that the entity doing the certifying is the political party.

Are you retreating from your statement that "there is no law that can be said to have been broken."?
