Incumbent Keith Self holds a commanding lead in the TX-03 race due to the district’s consistent Republican performance in recent cycles and his established position as Collin County judge before entering Congress. Rapid North Texas population growth and related pressures on infrastructure, housing, and data center development have surfaced as campaign themes, with challenger Evan Hunt emphasizing costs, schools, and local concerns while predicting a narrow margin. Self has dismissed debate overtures and focused on broader voter unease over prices and foreign policy. Forecasters rate the seat as solidly Republican, aligning with the current trader consensus. A major shift in national conditions, unusually high suburban turnout, or late developments on growth issues could still narrow the gap before the November 3 election.
