  • Republican U.S. Rep. Lisa McClain won’t face a primary challenger as she seeks re-election in Michigan’s 6th Congressional District
  • Democrat Clinton St. Mosley aims to challenge McCLain in the general election
  • The district is solidly Republican, with local voters backing Donald Trump over Joe Biden by 30 percentage points in 2020

LANSING — Republican U.S. Rep. Lisa McClain appears to be a heavy favorite for re-election in Michigan’s 9th Congressional District but will face a general election challenge from Democrat Clinton St. Mosley.

The district is mostly located in Michigan’s Thumb area and includes all  of Huron, Salinac and St. Clair counties, as well as parts of Tuscola, Lapeer, Oakland and Macomb counties. Major cities include Milford, St. Clair, Port Huron, Lapeer and Caseville.


McClain, now serving her second term in the U.S. House, easily won the district in 2022. She beat a Democratic challenger by roughly 30 percentage points to win re-election that year. 


Voters in the 5th District have reliably backed Republican candidates. Then-President Donald Trump beat Joe Biden by 30 points in 2020, and Trump trounced Democrat Hillary Clinton by just over 33 points in 2016.

McClain and St. Mosley were the only major-party candidates to file required petition signatures by the April 23 deadline. They’ll run unopposed in the Aug. 6 primary and will square off in Nov. 5 general election. Third parties can nominate candidates at conventions later in the year. 


Clinton St. Mosley: St. Mosley, who filed to run with a Lake Orion address, did not appear to have a candidate website as of late April. A Facebook page describes him as a father, husband and small business owner.



Lisa McClain: First elected to Congress in 2020 and re-elected in 2022, McClain lives in Romeo and has a bachelor’s degree in business administration from Northwood University. She was the founder and president of North End Support Team, an organization assisting Macomb County residents suffering from drug abuse and addiction, prior to jumping into politics. McClain currently serves as Secretary of the U.S. House Republican Conference. In Congress, she has opposed major Democratic priorities, including various spending plans and gun control measures. In early 2021, she voted to overturn election results in Arizona and Pennsylvania, both swing states where Biden had defeated Trump.
