Over the weekend, Ron Paul won Maine and Nevada, gaining 20 of 24 delegates in Maine, and 22 of 25 in Nevada.
In addition to the chaos that Paul will cause at the national convention, consider how this makes the average Republican caucus-goer feel. You make a good faith effort to vote, you leave the caucus with the impression that you elected a delegate loyal to your candidate, and then you find out that your vote didn’t matter at all because some Paulist used a technicality to essentially unseat the person for whom you voted.
