There is nothing unconstitutional about a state law requiring dlegates to be bound, as long as ALL political parties are covered by the same law.
Any State has a compelling interest to ensure the results of state primaries are carried out properly.
This is a 10th amendment matter, and the Federal Court has no jurisdicton here.
If you read the opinion, they had to invent a tortuous path to even opine on the subject.
The VA primary was March 1st.
Correll won election as a delegate in April, 2016, knowing full well the results of the primary election.
Then he claimed his First Amendment rights were being violated, which is complete crap.
No harm has come to Correlll, as the convention has not been held. But the Court butted in because there a reasonable expectation of prosecution if Correll followed his conscience.
The Court should have thrown the case out because Correll obviously became a delegate under false pretenses, and thus had no standing to sue for anything, especially since he suffered no harm to date.
