Any elected delegates are initially uncommitted, meaning they aren't bound to any candidate (unless after the primary a candidate gets 51+% of the vote, after which some delegates are bound to them.)
There were a few 'tickets' there that people were pushing, a ticket being a grouping of uncommitted delegates, running on a candidate or an issue or platform.
Mitt had one, we had one, and the pro-life/pro-family group had one.
First, someone got out the vote, and we suspect it was the LAGOP, which is ok. This would entail local candidates and regional candidates emailing their voters and friends, and getting them to come out and vote.
Once there, people look for a ticket. I'm not sure what drove them there, but the caucuses are not advertised on the local media as far as I can tell, so the only people who went got emailed by activists like us or pro-life groups or politically connected and inclined people. Some people may have come for only a few people, and may have used a ticket to supplement their vote.
The bottom line is that SOMEBODY (be it the LAGOP or other candidates) got out the vote and were able to channel people to one ticket. I think the establishment showed it's politically prowess last night. We depended on people to listen to rational reasons to vote for Ron Paul, and they relied on Nancy Reagan and the Gipper.
