Incumbent Michael Guest (R) defeated Michael Cassidy (R) in the Republican Party primary runoff in Mississippi’s 3rd Congressional District on June 28, 2022. Guest, who has represented this district in Congress since 2019, won with 67.4% of the vote while Cassidy received 32.6%. In the first round of the primary on June 7, Cassidy received 47.5% of the vote to Guest’s 46.9%.
Guest is a member of the U.S. House Homeland Security, Transportation, and Ethics Committees. He served as the district attorney for Rankin and Madison counties in Mississippi before his election to Congress. The Guest campaign highlighted his political experience and what they described as his conservative voting record in Congress. After the June 7 primary, Guest said, “I’ll be working to earn your vote because we need PROVEN, conservative leadership with a real record of fighting for our values—that’s the difference in the runoff election!”
Cassidy is a military veteran who said that he was running for Congress to continue serving his country. After the June 7, 2022, primary, Cassidy said “This is the first step in replacing our current congressman with someone who better represents [our] conservative Mississippi values.” According to Cassidy, “We need more people in Congress that will truly fight for the American people, and Michael Guest is quite simply not equipped for that challenge. He may be a decent man but he has proven to be ineffective at his job, and we need people who know how to fight in Congress.”
