Johnson/Weld's campaign would do best not to really discuss libertarianism but focus more on broad issues like term limits, campaign finance reform, and electoral reform.
Definitely, no one outside hardcore libertarians cares about the gold standard, splitting hairs on the Civil Rights Act (yeah, you Rand), or even Ending the Fed (Reserve). Those things you mention, ending corporatism and bringing back a real free market (jobs or starting your own business), reducing/eliminating domestic spying, curtailing/replacing/dismantling the TSA, etc would carry more interest right now.
