North Carolina’s 13th Congressional District illustrates the broader erosion of competitive seats in the U.S. House of Representatives. In 2022, Democrat Wiley Nickel won the district by approximately 9,000 votes. By 2024, Republican Brad Knott won the same geographic area by more than 70,000 votes. This shift resulted from redistricting by the Republican-controlled state legislature, which reshaped the district from a rectangular swing seat into an hourglass shape that excluded Democratic voters in Raleigh and incorporated rural counties near the Virginia border.
The transformation of the 13th District reflects a national trend. The number of swing districts—defined as seats where a presidential candidate won by 5 percentage points or fewer—dropped from 45 to 37 following recent redistricting efforts led by President Donald Trump. In 1964, there were 96 such seats. This decline means the majority of House members are effectively elected in primaries, with only a small fraction of the electorate deciding the general election outcome.
What the Right Is Saying
Republican strategists view the narrowed battlefield as a structural advantage that limits Democratic gains. Mike Marinella, a spokesman for the National Republican Congressional Campaign, described the contest as "a knife fight in a dark alley," suggesting that the limited number of competitive seats protects the GOP majority. "Both sides are fighting over a narrow House battlefield," Marinella said. Republicans argue that even in a difficult political environment, the structural advantage of safe seats prevents a large-scale shift in power.
Local Republican voters in the redrawn 13th District express confidence in their party’s hold on the seat. Linwood Parker, the mayor of Four Oaks and a lifelong Republican, acknowledged that gerrymandering is a long-standing practice in North Carolina, previously used by Democrats and now by Republicans. "Redistricting is just one of the levers that when Republicans, when they are in control, have to touch," Parker said. He compared the process to adjusting the rules of a baseball game to maintain fairness in competition. Voters like George Scott, a retired engineer who dislikes President Trump but remains a Republican, indicate that party loyalty persists despite dissatisfaction with national leadership.
What the Left Is Saying
Progressive advocates and Democratic leaders argue that the reduction in competitive districts undermines democratic accountability. Wiley Nickel, the former representative, stated that the primary divide in Congress is not between parties but between safe and competitive seats. "When your focus is on running a campaign where you talk to every single voter, you look at things differently and your focus is on solving problems," Nickel said. He introduced legislation to require nonpartisan redistricting in all states, though he ultimately left Congress to run for Wake County district attorney after determining he could not win reelection in the redrawn district.
Nick Troiano, executive director of Unite America, an organization advocating for electoral reforms, noted that 87% of the representatives elected to the House in 2024 were chosen by only 7% of the country’s voters. "Voters don’t have any way of holding Congress responsible, except for a narrow window of swing districts," Troiano said. He predicts that the lack of competitiveness will lead to "the least accountable and least representative Congress of our lifetimes." Democrats point to the unpopular war with Iran and high prices as factors that could expand the map of competitive seats, with national Democrats targeting districts like the 13th for potential upsets.
What the Numbers Show
Data indicates a significant decline in electoral competition. In 1964, there were 96 swing districts in the House. Recent analysis shows this number has fallen to 37. Unite America calculated that in 2024, 87% of elected House members were determined by primary voters representing just 7% of the national electorate. In North Carolina, only 15% of voting precincts are classified as politically competitive, according to Michael Bitzer, a political scientist at Catawba College.
Multiple studies cited in the reporting suggest that without partisan gerrymandering, the House would have approximately double the number of competitive seats it currently holds. In the 13th District specifically, President Trump received 58% of the vote in the new map configuration. Election returns from 2016 to 2024 show that no Democratic incumbent has retained a seat where Trump won 55% or more of the vote. These figures support the argument that the ideological sorting of voters and the drawing of district lines have created entrenched partisan strongholds.
The Bottom Line
The disappearance of swing districts contributes to increased polarization in Congress, as legislators prioritize the preferences of primary voters over the general electorate. Ian Shapiro, a political scientist at Yale University, stated that the decline in competitive seats produces "more alienation because Congress doesn’t do anything besides investigations and positioning." Shapiro estimated that even in a year with a significant partisan swing, such as 2006, the number of seats changing hands would be around 20, rather than the 40 seen in more competitive eras.
As the November elections approach, both parties are directing resources toward the limited number of remaining competitive seats. The 13th District remains a target for Democratic nominee Paul Barringer, a former healthcare lawyer who switched parties to run, hoping to attract voters dissatisfied with the current direction of the country. However, local dynamics and the structural advantages of the redrawn map suggest that the era of easy upsets in such districts has largely ended. The continued reduction of swing seats is expected to shape legislative behavior and accountability in the coming congressional term.
