Actually for truth in advertising the link you gave should be the political arm of Libertarianism, Libertarian Party, not the Cato Institute.
People can read the LP's pro-drug and basically pro-saddam rants there.
The drug issue makes this party seem cheap, at a time when this country never needed the Constitution more. And, maby that's part of the "con." Yet, I hope to help change that.
And, the Cato Instute does have the Libertarian philosophy!
