If Libertarians want queer marriage, legal drugs, abortion, high taxes, banned guns, no property rights, and a expanded Federal Government, they can vote for the RATS. The first one's been taken care of. Legal drugs are a consequence of less power to the government and more to the people (with personal responsibility). High taxes, gun banning, restrictions on property rights and expanded federal government are all anathema to libertarians.
Their platform contains the ideas of the far ends of both major party's. That might be why they are at a loss to get over 1% of the vote?
