Incumbent Rep. Jim Baird commands 72% trader consensus as the IN-04 Republican primary winner on May 5, bolstered by incumbency advantages, name recognition, and fundraising exceeding $140,000 since early 2025 in this solidly Republican district. State Rep. Craig Haggard holds 10% implied probability after ramping up his challenge in mid-March, appealing to conservative voters amid scrutiny of Baird's age (80), post-January car crash health recovery, and nepotism rumors involving son Beau Baird. Longshot John Piper sits at 0.6% following his early March announcement, with no public polls available to gauge voter turnout or swing voter dynamics in the closely approaching contest.
