Unlike the the Major Parties which can use their influence to extract large contributions from the wealthy, the Libertarian Party is dependent on people like you paying dues. So please take the time to join at all three levels, and give more if you can.
When you register to vote Libertarian you make a statement that often you cannot make in the voting booth, either because we weren't able to field (or were prevented from doing so) a candidate or because the voter feels choosing the lesser of the evils is more imminently important.
