I prefer an open primary to any other option. A closed primary with same day registration is acceptable to me because any who wants to participate can suck it up and sign up with the party of the candidate of their choice. The point of view that a primary is a party function and you should be a member of the party to participate does hold some validity. A closed primary that requires you to be registered in advance makes it more difficult for new voters to get involved in the process.

The ease with which an open primary or same day registration allow new participant to join the process outweighs the risk of people maliciously disrupting the process in my opinion.
