Incumbent Republican Jim Baird secured his party's nomination in the May 2026 primary for Indiana's 4th congressional district, facing limited intra-party opposition in a seat that covers west-central Indiana including Lafayette and western Indianapolis suburbs. The district's consistent Republican voting patterns, demonstrated by Baird's 64.8% general election margin in 2024, underpin the current trader consensus favoring the Republican nominee. Democratic primary contenders, including Drew Cox, have not altered the underlying partisan composition or produced polling shifts. Factors that could narrow the gap include an unexpected national political environment, candidate-specific developments such as health or ethics issues, or unusually high Democratic turnout in the November 2026 general election.
