Arkansas State Senator Ron Caldwell has secured his fourth term with a victory over political newcomer Trey 'BoDirt' Bohannan in the Republican primary. The primary was particularly notable due to controversy over a controversial prison project backed by Governor Sarah Huckabee Sanders, which led to Caldwell's opposition to funding for a proposed 3,000-bed prison. With no Democratic challenger in November, Caldwell's victory reaffirms his role as a key conservative voice in the state.
