Incumbent Steven Palazzo and Mike Ezell are running in the June 28 Republican primary runoff for Mississippi’s 4th Congressional District. In the June 7 primary, Palazzo received 31.6% of the vote, while Ezell received 25.1%. Both candidates advanced to a runoff because no candidate received more than 50% of the vote.

Palazzo was first elected to the U.S. House in 2010. From 2006 to 2011, he served in the Mississippi House of Representatives. Palazzo said voters should choose him because of his experience in Congress, relationships at the state, local, and federal levels, and seat on the House Committee on Appropriations. Palazzo said, “If we lose this Appropriations seat, we will not get it back.” Palazzo also said, “I’m the one with the proven track record. I’ve been working hard for south Mississippi for over 12 years. Look, $26 billion for 26 ships since 2011, fighting for our men and women in uniform, helping to secure funds for the wall on our southern border. I think I’ve been an effective legislator for south Mississippi.” Louisiana Rep. Steve Scalise (R) and National Right to Life endorsed Palazzo’s re-election.

Ezell is the Jackson County Sheriff, a position to which he was first elected in 2014. Ezell has campaigned on protecting the 2nd Amendment, securing the border, and growing the economy. Ezell has said voters should choose him because of his law enforcement experience: “From the chaos and crisis on our southern border to the crime and drugs that are hurting so many communities across our country, it’s going to take someone in Congress with real law enforcement experience to tackle these issues that affect all of us.” The candidates who lost in the June 7 primary—Clay Wagner, Brice Wiggins, Carl Boyanton, Raymond Brooks, and Kidron Peterson—endorsed Ezell.

Allegations that Palazzo previously misused campaign funds have been an issue in the primary, with Ezell saying, “Steven Palazzo has been under the cloud of an ethics investigation.” In 2020, the Office of Congressional Ethics released a report that said the allegations should be further investigated because “there is substantial reason to believe that Rep. Palazzo converted funds to personal use to pay expenses that were not legitimate and verifiable campaign expenditures attributable to bona fide campaign or political purposes.” Palazzo has denied the allegations. Palazzo’s campaign spokesman said, “All of this from the beginning was political, created by Congressman Palazzo’s political opponents…We’ve long been ready to get this behind us and we fully believe it will be resolved in Congressman Palazzo’s favor.” The House Ethics Committee‘s review of the allegations is ongoing.
