Someone will need to prove to me that this is Virginia LAW, as contrasted with Virginia Republican Party Rules.
It would appear that if this is the case, that the Commonwealth of Virginia has enacted one set of rules for Republicans and another for Democrats. That alone sounds like an infringement of the equal protection clause.
Good point. There are issues that need to be resolved, such as if the state GOP changed the rules unfairly, or administered the rules unfairly. This should be resolved by a court. If the state GOP acted fairly, they will be vindicated. If not, then Perry will.
