The Race

Rep. Nikki Budzinski (D-IL) is running for a third term in Illinois' 13th U.S. House District, a seven-county seat that runs from Champaign-Urbana through Decatur and Springfield down into the Metro East suburbs of St. Louis. She was the first Democrat to hold it since 1895, winning it in 2022 after the state's remap redrew the district around those population centers. Budzinski defeated challenger Dylan Blaha in the March 17 Democratic primary with 44,763 votes to his 14,850, or 75.1% of the 59,613 ballots cast.

Jeff Wilson, a Champaign County Board member and retired Navy nuclear submarine officer, won the Republican nomination with 22,291 votes to Joshua Loyd's 10,733, or 67.5% of 33,024 cast. Loyd is a familiar name here. He was the Republican Budzinski beat 58% to 42% in 2024, and this time he lost his own primary before getting another shot at her.

Wilson, who lives in Mahomet, just outside the district in neighboring IL-15, argues the seat is winnable on affordability and cost-of-living. Illinois does not require House candidates to live in the district they seek.

Ratings

The Cook Political Report rates Illinois' 13th Solid Democratic. Inside Elections places it in the same tier, and Sabato's Crystal Ball calls it Safe Democratic. Different vocabulary, same verdict: none of the three counts this district as competitive.

Cook also puts the district's Partisan Voting Index at D+5, which is a lean rather than a fortress. The gap between that D+5 and a Solid rating is Budzinski herself. She won by 16 points in 2024 in a district Kamala Harris carried by 11, meaning she ran about 5 points ahead of the top of her own ticket.

Prediction Markets

Polymarket traders put the Democratic Party at 94% to hold the seat and Republicans at 7%, as of Monday, July 27. The two add up to 101% because market prices carry the spread between buyers and sellers rather than splitting probability cleanly, and with only about $11,088 traded here, a single large bet can move the number.

Experts vs. Markets

A D+5 seat in a strong national environment for the out-party is the kind of race that occasionally gets interesting. What keeps this one off the board is a two-term incumbent who has now outrun her district's partisan lean twice, against a challenger who has never run statewide or federally and who beat a man Budzinski had already dispatched by 16 points.

Wilson's counterargument is that affordability cuts across the partisan math. The market gives that case 7%, which is not nothing, but is also drawn from a pool of only about $11,088. That's the honest caveat on both sides of this one: the forecasters and the traders are looking at the same short list of facts, and neither has much new information to trade on until Wilson gives them some.
