Who has already voted and how?

I think if one is that committed to not joining a party, one shouldn't be able to pick that party's nominee.  In other words, if joining a party for the primary and then leaving after is too much work, you probably shouldn't be choosing who that party's nominee is.

I really don't like the idea of rewarding tampering from people who don't intend to support the nominee in the general anyway.

And a party should only allow a nominee from within. Bernie?

I have no objection to Bernie joining the party every four years to run in the presidential primary.  It's certainly better than if he ran third party!

But I would expect that Democratic voters would view him less favorably for not being a "real" Democrat, and it looks like they do.
