On July 7, a U.S. District Court heard arguments in Correll v Herring, e.d., Virginia, 3:16cv-467. This newspaper story describes the hearing, although it does not say anything about which way Judge Robert Payne appeared to be leaning. The article says there will be no decision today. The issue is the Virginia law that requires delegates to national conventions to vote for the presidential candidate on the first ballot who had won Virginia’s presidential primary. UPDATE: here is a more detailed news story from the Washington Post.
Based on case law, this case is likely to succeed. The U.S. Supreme Court, ever since 1972, has struck down state laws that tried to influence how national political party conventions are run.
