Rep. Michael Guest wins Mississippi primary runoff

State of play: Guest lost to Cassidy by almost 300 votes in the June 8 primary, but neither candidate received 50% of votes needed to avoid a runoff.

• Guest after the primary received an onslaught of support from his Republican colleagues in Washington, including from the Congressional Leadership Fund, a super PAC aligned with House Minority Leader Kevin McCarthy, Roll Call reports.
• Guest also sought to clarify his positions that came under attack by Cassidy, a Navy veteran, specifically surrounding his support for the bipartisan commission and has rejected Cassidy's claims that he was disloyal to former President Trump, AP reports.
• Trump did not make an endorsement in the race, but the former president's allies, including Stephen K. Bannon, referred to Guest as "one of these lame never-Trump guys" on his podcast, the New York Times reports.

The big picture: Guest's victory comes as the 35 Republicans who voted to create the commission are largely facing retribution over their vote — or they've retired, Axios' Andrew Solender reports.

• Almost a third of the House Republicans who voted for the commission either plan to retire this cycle, already resigned or lost their primary.
