Duncan is in his 4thterm representing the 3rddistrict in the north and west of South Carolina. He sits on Energy and Commerce, and is a member of the Republican Study Committee. In a conservative state, Duncan ranks at the top of the delegation, sporting an excellent 95.6% legislative score. Quite a few of his colleagues talk a conservative game, Duncan is one of the few who actually votes it. He deserves continued support.
