Incumbent Republican Marlin Stutzman holds a commanding position in Indiana’s 3rd congressional district due to the seat’s consistent Republican tilt, reflected in a Cook Partisan Voter Index of R+16 and Donald Trump’s double-digit margins in recent presidential contests. Stutzman, who previously represented the district and won the 2024 general election, secured the Republican nomination with 68% in the May primary and benefits from substantial fundraising of roughly $840,000 compared with Democrat Kelly Thompson’s $136,000. Forecasters across outlets rate the race Solid or Safe Republican, with early voting underway ahead of the November 3 general election. Thompson, who advanced unopposed in her primary, faces structural barriers in a district that has not elected a Democrat in decades. Trader pricing at 95% for Stutzman aligns with these fundamentals, though late developments such as a major scandal, health event, or unforeseen national shift could still alter the outcome before certification.
