I don't think he's ever said if he carries concealed, and frankly, I don't think that's something that should be public knowledge any more than whether you or I carry.
Open, concealed, as long as he’s on board with the concept.
You have to admit though, a candidate standing on stage with a well tooled leather holster peeking out from under his/her suit coat would solidify a lot of support amongst gun nuts like myself.
Blaze orange and a brand new trap gun don’t impress me. Blued steel with shiny spots on the high points and a well broken in holster? Now that would impress me.
