Indeed, as Harry Cheadle writes:
Since the party’s 2012 defeat, there’s been a lot of talk in political publications about how to “fix” the GOP. Generally, writers have recommended that Republicans run candidates that have libertarian views on social issues so they can appeal to young people, which dovetails with an idea circulating in the blogosphere called “libertarian populism.” The latter is basically an ideology that is pro-free market, anti-interventionist when it comes to foreign policy, and opposed to both big government and big corporations. Those might be good ideas, but they don’t seem to have a constituency beyond a bunch of bloggers who need something to debate in between elections, and there has yet to emerge a flesh-and-blood candidate who is running for office on a libertarian, anticorporate, antiwar platform. The Republican Party hasn’t embraced libertarianism for the simple reason that the people who belong to the party and vote in its primaries aren’t libertarians.
