Over at the 35th LD blog there is a lengthy and (it reads at least) angry post on open primaries and how a lot of Republicans must have jumped over to vote D to push Sheldon last week. I don't doubt that, but I have a problem with the authors contentions. So, I left a comment.
I fear Eric is correct, that is really isn't all that important for one to befriend the local LD or county organization to win an election. Though, I don't think this problem is soley Democratic.
My contention is that local parties need to be broader in terms of who plays. More participatory, more focussed on civic engagement and less on winning elections.
