I am a (small "l") libertarian. I believe there are many paths to advance the cause of liberty and I support anyone who spends their energy advancing the cause, whatever path they take.
For me, the most effective path was to run for office as a Republican, following the model that Dr. Ron Paul and Sen. Rand Paul have built. As a Republican, I've been able to win election and serve two terms fighting for liberty in the Maine State Senate.
