Four Democrats Battle for Chance to Challenge Rep. Mackenzie in PA-7
Four Democrats compete in primary to challenge GOP Rep. Ryan Mackenzie in swing district that could determine House control.

ALLENTOWN, PENNSYLVANIA β Four Democratic candidates are competing in a primary election to challenge Republican U.S. Rep. Ryan Mackenzie in Pennsylvania’s 7th Congressional District, a swing region that national Democrats view as essential to reclaiming the House majority.
The Democratic contenders include Bob Brooks, president of the Pennsylvania Professional Firefighters Association; Ryan Crosswell, a former U.S. Department of Justice prosecutor; Lamont McClure, an attorney who served eight years as Northampton County executive; and Carol Obando-Derstine, an engineer and former U.S. Senate staffer.
Competitive Swing District
The 7th Congressional District encompasses Lehigh and Northampton counties and portions of Carbon and Monroe counties in eastern Pennsylvania. The district includes the cities of Allentown, Bethlehem and Easton, which together form the commonwealth’s third-largest metropolitan area.
Political analysts describe Pennsylvania’s Lehigh Valley as one of the nation’s most competitive swing regions. While Carbon County remains reliably Republican, Lehigh, Monroe and Northampton counties have demonstrated volatile voting patterns over the past decade.
These three counties supported President Donald Trump twice but shifted to elect Democrats in three of the last five general and presidential elections, according to the Pennsylvania Capital-Star.
National Democratic Target
The Democratic Congressional Campaign Committee has identified the 7th District as one of four Pennsylvania seats key to their strategy for winning House control. Mackenzie’s victory over his previous Democratic opponent was decided by just 1% of the vote two years ago.
The district represents one of 44 Republican-held seats nationwide that the DCCC has targeted as part of their plan to flip the four seats Democrats say they need for a House majority.
A dark money political action committee called Lead Left has invested more than $2.2 million in the primary race, showing the national attention focused on this competitive district.
Electoral History and Stakes
The Lehigh Valley’s swing nature makes it a bellwether for broader political trends in Pennsylvania. The region’s combination of urban centers, suburban communities and rural areas creates a diverse electorate that has proven unpredictable in recent election cycles.
National Democrats are focusing on districts like Pennsylvania’s 7th to build the coalition necessary for regaining House control. The primary winner will face the challenge of appealing to the district’s varied constituencies while mobilizing Democratic voters in what promises to be a closely watched general election campaign.
