I used to consider myself a republican, years ago. Then I decided I was too Conservative for the GOP. Now I consider myself a Libertarian, to a point. I guess, all things being equal, I’m a strict Constitutionalist.
I don’t think most Libertarians are out to destroy the GOP, I think many just want to be free, unlike the dems and GOP.
I have never been a republican, nor a member of your GOP.
What libertarians are out to destroy is conservatism, conservatives are having to fight the left whether they call themselves moderates or libertarians.
Either way, the left grows and has many different uniforms to seduce people with, the coolest for the indoctrinated young and the Bill Mahers, is to be libertarian, that way they can remain liberal and still complain about taxes.
