According to preliminary election data analyzed by the Associated Press, the 2026 midterm elections saw an unusually high number of races decided by large margins. As of July 31, 2026, final certified results from several states indicate that over 70% of House races were won by more than 10 percentage points, a record in modern history.
Political analysts attribute this trend to a combination of gerrymandering, partisan polarization, and the nationalization of local elections. "Voters are increasingly choosing based on national issues rather than local candidates," said Dr. Emily Thompson, a political scientist at the University of Virginia. "This leads to fewer competitive districts."
The data also shows that Senate races were similarly lopsided, with only three out of 35 races decided by less than 5 points. This continues a trend observed in previous cycles, but the magnitude in 2026 is unprecedented.
Critics argue that such landslide victories reduce accountability and voter engagement. However, turnout in competitive districts was actually higher than in safe districts, suggesting that voters still care about the few races that are close.
