I think Indiana should have picked up on that prior to the time of the election.
Verification paperwork is not murder, and I think 2 years is the time one has to take paperwork to court for redress.
Just in my humble and unknowing opinion based on facts that used to be relevant, lol.
sorry, my friend, I can't help you on this one. It would take a scholar of Indiana state laws and United States laws to tell.
If nothing else, the Republican Party had better develop some semblance of checking on each and every state to be sure paperwork is in order several weeks before an election begins.
