The Illinois 15th congressional district's strong Republican lean, reflected in consistent "Solid Republican" or "Safe Republican" ratings from major forecasters and a 22.5-point Trump margin in 2024, anchors trader consensus around incumbent Mary Miller. She secured her March 2026 primary with over 73% of the vote and holds a substantial fundraising edge with more than $833,000 in cash on hand compared to challenger Jennifer Todd's roughly $9,000. Todd advanced from a low-turnout Democratic primary but faces structural barriers in a rural, agriculture-focused district with limited Democratic infrastructure. Late developments such as a major scandal, health event, or national political realignment could still shift the race before the November 3 general election.
