During the nomination season for the state GOP, the popular vote in the primary phase gave a big victory to former Sen. Rick Santorum, and a smaller win to presumptive nominee (by party rules) former Gov. Mitt Romney. But party activists during the caucus phase gave a majority to Rep. Ron Paul. As noted, any whining by the conservatives in the party was unwarranted by the fact they had the chance to follow the rules as did the libertarians.
Yet with the shoe on the other foot, now it's the libertarians who complain about the rules of the process. Statements from their leaders moan about unfairness with rules promulgated only days before the convention was to meet by the Louisiana Republican State Central Committee that would allow the convention to meet with only a third present (Paul forces had 62 percent of the delegates), which is not unusual (I have served on bodies where that proportion served as a quorum) and others in order to maximize the chances that only genuinely-committed delegates for candidates other than Paul are selected for those candidates.
