No, not really. Their agenda fits nicely on the left (open borders, drugs for everyone, George Soros' agenda.)
I agree their stands on illegal immigration & defense are ridiculous. However, if you look at other countries that are NOT fighting an absurd, counter productive and futile "war on drugs" they are doing pretty darned good. Amsterdam is not the debacle everyone predicts will happen if we legalize drugs. Actually, if you take out the Muslims, its a lot safer than LA, etc.
No, not really. Personal responsibility is a big part of libertarianism. Something that is sorely lacking in both the democratic and republican parties. The l's aren't interested in micromanaging your life as long as you aren't depriving anyone of life, liberty or property through force or fraud.
