I'm from the opposite pole. I'm a liberal who feels that the Democrats are mostly incompetent and that liberalism itself is going down the tubes. I see the Libertarian Party as an effective tool for pressuring the two major parties into paying more attention to liberties.
My issues with the LP are with its demographics more than its platform. Too many within the party are either so idealistic as to have lost touch with reality or just basically disaffected Republicans. As a result allying with them feels much like cutting off my nose to spite my face.
If they start thinking more realistically and if conservatives start noticing the differences between themselves and the concept of libertarianism, the party would certainly suit my needs. As it is, it is just a tool for me to use to send a message to the Crats that lose my vote.
