Ted NEEDS to take care of this NOW!!!!!
This is a non-starter. He has taken care of it by getting on the ballot. He is not going to sue himself...if he somehow did that then Trumpsters will say he didn't put forth a strong enough case against himself.
Perhaps a refresher course in jurisprudence is in order. Ted is already on the ballot in most states. It would take a suit against him to take him off, which would make Ted the defendant in this case.
Furthermore, it is the States that elect the President, thus it is a State issue - not a federal issue. Democrats would have to file 50 separate suits between the Convention and the December election.
