I understand Ron Paul's policies and agree with some of them, but I just straight up don't like him.
Libertarians have been around for a long time, but in general they have a hard time screening candidates for backgrounds and/or craziness. Saw that problem a couple years ago during our gubernatorial race that a good friend of mine got involved in. Many of the normal party volunteers get fed up and return to the Republican Party. People also tend to get more socially conservative as they get older and start families.
