KEY TAKEAWAYS: Cleo Fields wins Democratic primary unopposed in **Louisiana’s 6th District, including Alexandria, Baton Rouge, Lafayette and Shreveport. Clay Higgins wins Republican primary unopposed in the 3rd District, covering Lake Charles and Houma. Both candidates automatically advance to the Nov. 3 general election after the Feb. 11–13 qualifying period. Supreme Court of the United States reviewing district constitutionality; Fields told USA Today Network he wants a definitive ruling.   Louisiana Democratic Congressman Cleo Fields and Republican Congressman Clay Higgins have been elected without opposition in their May 16 party primary elections, though both will face opposition in the Nov. 3 general election. Fields represents the 6th District with sprawling boundaries that include all or part of four of the state’s largest 10 cities including Alexandria, Baton Rouge, Lafayette and Shreveport. Higgins represents the 3rd District with boundaries that include all or parts of Lafayette, Lake Charles and Houma as the population centers. Both Fields and Higgins automatically advance to the Nov. 3 general election after no other candidates qualified for Fields’ Democratic Party primary or Higgins’ Republican Party primary during the Feb. 11-13 qualifying period. In the general election, Fields will face the winner of the 6th Congressional District Republican Party primary, which includes four qualified candidates, while Higgins will face the winner of the 3rd Congressional District Democratic Party primary, which includes three qualified candidates. Fields told USA Today Network he is “grateful” to win his primary, but that he will “continue to work to earn” another term in the general election even as the future of his district boundaries are under scrutiny by the Supreme Court. Fields won the seat two years ago after Louisiana changed its congressional boundaries to create a second majority-Black district in the 6th District. The constitutionality of those boundaries is being challenged in the Supreme Court. “I think people want a final, definitive decision from the Supreme Court,” Fields said. “It’s my belief that the boundaries are constitutional, but it’s important to have certainty once and for all.” Greg Hilburn covers state politics for the USA TODAY Network of Louisiana.
