I feel like the LP has become more and more of what you describe since Ron Paul's 2008 campaign and the Tea Party emergence
The thing is the Libertarian party’s independence from the Republican party is under threat. They’re withdrawing from even safe R races just because the Mises caucus hates democrats and selling their headquarters, they’re risking to become separated and divvied up to what the constitution party is now or what labor and the Vermont progressives are to the democrats. It’s sad what could have been is being strangled by the current leadership.
