VotePredictor forecast
Republicans hold the seat either way
Both finalists are Republicans; the model forecasts a Democrat against a Republican, so it does not pick between them.

Forecast spread
±6.6 points

Margin from the district's presidential lean on its 2026 lines, one fitted intercept and the national environment as a uniform swing; the win probability adds a decaying incumbency premium (Republican incumbent running). No district poll is blended in.
