Incumbent Republican Marlin Stutzman drives the 90.5% trader consensus for a Republican win in Indiana's 3rd Congressional District, bolstered by the seat's R+16 Cook Partisan Voting Index—ranking it among the nation's safest GOP holds—and his 65% general election victory in 2024. With the May 5 primary approaching, Stutzman faces token challenger Jon Kenworthy amid superior fundraising ($188,000 cash on hand versus Democrat Kelly Thompson's $13,000), while Thompson runs unopposed on the Democratic side. Forecasters like Cook Political Report rate it Solid Republican. Upsets would require a Stutzman scandal, primary loss, or extraordinary national Democratic midterm wave with surge turnout, though historical base rates for such shifts in deep-red districts remain low.
