Oh GOP isn't losing libertarian voters, they vote on specific issues and individules. If GOP candidates wants them they have to run like true Republicans.
The Republican Party has to become more libertarian in many areas especially spending. One area they cannot go the liberatrian route is immigration--that will be a loser. I have voted LP in the past because the Republican candidate wasn't viable to begin with (they rarely are in NY). Unfortunately the LP is seen as a joke in many Republican circles. In NY I have to agree, only because of the crazy stances they take. Maybe in other areas of the country the LP is saner.
