>>I call him a libertarian.
That’s an accurate label in my view. Nonetheless, libertarians are part of the right, even though they may not be conservative. And so conservatives can make common cause with libertarians on many issues.
Most libertarians vote for conservatives because it is the “most libertarian” choice at the ballot box. I have no difficulty voting for a libertarian if he or she is the candidate most aligned with my beliefs.
Mostly economic. Libertarian social beliefs are way beyond my own. And, yest, I AM a conservative, both economically ans socially.
