Incumbent U.S. Rep. Jim Baird dominates trader consensus at 88.8% implied probability for the May 5 Indiana 4th Congressional District Republican primary, driven by his long-held seat since 2019, Vietnam veteran status, and high-profile endorsement from President Donald Trump, alongside backing from Rep. Jim Jordan and Indiana Farm Bureau. State Rep. Craig Haggard garners 9.1% on momentum from Attorney General Todd Rokita, retired Marine Gen. Jon Davis, and over 100 local officials emphasizing his ground game and rural focus, while newcomer John Piper lingers at 1.2% with fringe messaging. Early voting is underway amid candidate forums, but absent polls or scandals, incumbency advantages and historical primary win rates above 90% sustain Baird's lead ahead of election day.
