A big reason why I can't support the Libertarian party is right there.
The big reason I can't support the libertarian party is that I've read their platform. I also found their position on 9/11 to be absurd. Harry Browne, who has now passed away, was their party candidate for president in 2000. His position on 9/11 was that we should 'follow the constitution' and 'issue Letters of Marque and Reprisal'. In effect, he wanted to hire bounty hunters to respond to Al Qaeda.
