Indiana — 5th District

I’ve been loosely keeping an eye on Indiana’s 5th Congressional District the past few weeks, after a tipster in Indiana suggested I start paying attention.

By all rights, this should be a comfortable seat for Republicans to hold, even in a seeming blue wave election. Donald Trump won the district by more than 17 points in 2024, and incumbent GOP Rep. Victoria Spartz took it by more than 18 points in the same election.

The national Democratic edge today in the average congressional generic ballot is about nine points, meaning that a shift of that scale in Indiana’s 5th would still enable Spartz to win comfortably.

Meanwhile, Indiana is about as far as you can get from a focus of national attention in the midterms. It lacks races for Senate or governor this year, and the U.S. House contests are largely snoozers. The biggest race on Indiana’s 2026 ballot is for secretary of state (though to connoisseurs of downballot races, it’s a doozy).

No surprise, then, that when I started paying attention to the race, the 5th District contest continued to languish in the leading handicappers’ Safe Republican categories. In recent days, the Cook Political Report with Amy Walter and Inside Elections have moved the seat to Likely Republican; Sabato’s Crystal Ball still has it at Safe Republican. None of the three has it in a genuinely competitive category.

They may be right that there’s nothing to see here. Still, there have been signs of greater-than-expected ferment.

In the May 2026 primary, Spartz’s opponent, veteran Scott A. King, took 40% of the vote in a two-way race; King narrowly won the votes from Delaware County (Muncie) outright. That’s after a campaign when King was essentially an unknown and had few resources to work with.

In the general election, an internal poll from Democratic challenger, former state Sen. J.D. Ford, found Spartz with just a two-point lead. Spartz’s recent email communications have taken a more aggressive tone than one might expect from someone running a shoo-in race, including complaints about allegedly stolen yard signs and AI-generated attack ads against her. She’s even asked Ford for a debate, so far unsuccessfully — an unusual dynamic for a safe incumbent.

Biography and geography may also be playing a role in the race’s dynamics. Spartz has sometimes been a thorn in the side of her own party, refraining from voting in favor of must-support bills until the very last minute. Meanwhile, her district, despite Trump’s sizable edge, has the closest division of any GOP-held congressional district in Indiana, and it’s affluent. Hamilton County (Noblesville and Carmel) has attracted suburban outflow from Marion County, which is coterminous with Indianapolis. Hamilton County has the highest median household income in Indiana — the type of Republican demographic that has felt disproportionately alienated from the party’s MAGA turn.

“Hamilton County is turning more purple because of turnover, big expensive apartments and condos in Carmel and Fishers, and now Westfield and Noblesville, and lots of young people in tech and biotech industries moving in,” said one political observer in the state. “About a quarter of the Fishers population is now also foreign born. All the new folks don’t know they are supposed to vote Republican, and if they do, they like candidates like” pragmatic former Gov. Mitch Daniels and former Sen. Dan Coats, not the MAGA-aligned Gov. Mike Braun and Sen. Jim Banks.

As I was deciding whether to write about this race — as a possible sleeper contest in a blue wave environment — an embargoed poll landed on my desk.

The poll was conducted for Free Press Indiana by Bellwether Research, headed by Christine Matthews, an Indiana native who has polled in the past for Republicans, though usually the moderate type.

The statewide poll of 839 likely voters, with data being released this morning, found Trump under water in approval, 44%-54%. Asked whether they were more enthusiastic about voting this year, 58% of Democrats said yes, compared to 34% for Republicans and 24% for independents.

Most strikingly, Democrats had a one-point lead in the generic congressional ballot. That’s in a state with seven strongly Republican districts, one narrowly Democratic district and one safely Democratic district. (State senators resisted a Trump-inspired mid-decade redistricting plan that would have drawn nine safe Republican districts.) The self-identification by party in the poll overall was 49% Republican, 40% Democratic and 11% independent, which makes the congressional ballot result notable.

The poll didn’t specifically survey Indiana’s 5th District.

I asked Matthews for what stuck out at her about the findings.

“Looking back on all polling I’ve done in Indiana and other public polls, I have not seen in the Trump era where his disapproval was this high,” she said. The poll suggests there’s “no reason to think Indiana is immune from what’s happening in other red states.”

She said the affluence and high education levels of the 5th District should be a warning sign for Spartz. It was already the “least Trumpy” of the state’s Republican-held districts.

Matthews particularly noticed that college-educated men, who accounted for about one-fifth of respondents statewide, said they would vote Democratic for Congress by a 50%-42% margin — an impact that would hit especially hard in the 5th. (College educated women, accounting for another 22% of respondents statewide, backed a Democrat by a 62%-31% margin.)

Maybe the polling is off. Maybe Spartz will coast to victory. But if a seat that’s rated Safe or Likely Republican today can legitimately become a battleground race between now and Election Day, Democrats might be looking at midterm House gains on the higher edge of expectations. Even if a Democrat can’t quite pull off a win in this Trump +17 district, an equivalent showing could tilt a bunch of other races in slightly less red districts.
