Lambert Boissiere III faces a runoff Saturday in his reelection bid for Louisiana’s Public Service Commission. Boissiere’s challenger is Davante Lewis, a 30-year-old progressive policy advocate. Both candidates are Democrats with similar views and priorities, including expanding Louisiana’s renewable energy. The winner will serve a six-year term representing a district that stretches from Baton Rouge to New Orleans. The five-member commission has regulatory jurisdiction over public utilities providing electric, water, wastewater, natural gas and certain telecommunications services in Louisiana.
