Livingston went for Vitter by a small margin, but Ascension, for Edwards.
Ascension has a large labor union population that work in the petrochemical industries on the Mississippi River. I own some property in that parish, inherited from my Mother who grew up there. My Father was from the area, too. Have lots of kinfolk there.
Lincoln Parish went for Edwards, but Jackson Parish (blue collar) went for Vitter. Lincoln is heavily infested with deadheads that have jobs at Louisiana Tech University and Grambling State. Typical government employees that only are concerned with their retirement and medical bennies.
Bossier went Vitter; Caddo, Edwards.
