Establishment GOP does not have the votes or the money in primaries. People do. I do not understand why we allow open primaries. Only registered republicans should select our nominee.
I support caucuses in which party registration is required to vote — or at least I did before the debacle two days ago in the Missouri caucuses with police having to be called to shut down one of the state's largest caucuses in St. Charles County.
However, we need to remember that not every state has voter registration, and in some which do, registration is virtually meaningless because it can be changed up until the day of the primary. Every state is a little different on their procedures, and for those of us who as Republicans support states’ rights, I don't think we want the national GOP ordering state parties what to do.
Open voting needs to stop, but it needs to be a state-by-state decision on how to stop it.
