Are you kidding me? Olympia Snowe, Lindsey Graham, John McCain, Chris Cristie, Susan Collins, and pretty much every one of them currently voting with the Democrats.
All of the Rino establishment types are pretty much Libertarians. Not overtly, but by their voting records and policies it is apparent.
You’ve just proven you have no idea what libertarians stand for. Snowe? Christie? Graham? This is simply too wrong to discuss. Look up the term “libertarian”; gun rights are central. None of the ones you offered as examples are remotely libertarian.
