From the end of the Reconstruction in 1877 until the appointment of John Hainkel in 2000, the senate chair was held by Democrats. During this time most lieutenant governors were allies of the Governor, with notable exceptions. During this time several senate presidents pro tempore became acting lieutenant governor due to the premature vacating of the office of lieutenant governor. On at least two occasions it was due to the ascension of the lieutenant governor to the governorship, in the case of the others it was because of the death, resignation or removal of the lieutenant governor. When the seat was vacated the president pro tempore became acting lieutenant governor in accordance with the constitution, and on two occasions the president pro tempore became governor. In 1976, with the implementation of the Louisiana Constitution of 1974, the lieutenant governor assumed executive duties and the gavel once again passed to a senate-elected president. 1976 also saw Virginia Shehee become the first woman elected to the Louisiana State Senate.
