Indiana’s Other Congressional Battles: Seven House Races to Watch in November 2026

Red GOP; Blue Dems

INDIANA — With Indiana's May primaries settled, the state's congressional ballot is taking its final shape for the November 3, 2026 general election. Every one of Indiana's nine U.S. House seats is on the ballot, but the political terrain varies dramatically from Northwest Indiana to the Ohio River.

Hoosier Enquirer has separately examined the races in Indiana's 2nd and 3rd Congressional Districts. That leaves seven contests — Districts 1 and 4 through 9 — that will help determine whether Indiana sends essentially the same partisan delegation back to Washington or produces an upset somewhere on the map.

Republicans currently control seven of Indiana's nine House seats. Democrats hold two. National election handicappers see relatively little genuine competition across the state, with the 1st District in Northwest Indiana standing out as Indiana's most obvious potential battleground.

Still, several of these races deserve a closer look.

District 1: Frank Mrvan Faces the Race Republicans Want

The most consequential Indiana congressional contest may again be in the northwest corner of the state.

Democratic incumbent Frank Mrvan faces Republican Barb Regnitz in a district stretching across Northwest Indiana and centered on Lake and Porter counties. Ballot listings also identify Alexander Degman and James Johnson as general-election candidates.

Mrvan occupies a seat Democrats have managed to preserve even as much of Indiana has moved decisively toward Republicans. The district's industrial history, organized-labor presence and Democratic strength in portions of Lake County have made it fundamentally different from most of the state.

But Northwest Indiana isn't politically frozen in time.

Republicans have made gains in the region, particularly outside the traditional Democratic strongholds, while national arguments over immigration, energy, manufacturing, inflation, crime and President Donald Trump could make this contest significantly more interesting than most of Indiana's other House races.

That makes Regnitz's challenge one to watch. If a Republican congressional wave reaches Indiana in November, District 1 is the logical place to look for evidence of it.

It is also the Indiana district that national observers currently identify as the state's principal competitive opportunity. In 2024, it was Indiana's only congressional district decided by less than 10 percentage points.

For Mrvan, the strategy is straightforward: maximize Democratic turnout in Lake County while remaining competitive enough in Porter County and elsewhere to prevent Republicans from building an insurmountable suburban and exurban advantage.

For Regnitz, the equation runs in reverse.

Of Indiana's congressional races, this is the one HE would presently circle in red.

District 4: Jim Baird vs. Drew Cox

Western Indiana's 4th Congressional District gives voters a sharp contrast between Republican incumbent Jim Baird and Democratic nominee Drew Cox.

Baird survived a Republican primary challenge after receiving approximately 60.5 percent of the GOP vote. State Rep. Craig Haggard finished second with roughly 30.5 percent. Cox emerged from a much more crowded Democratic primary with approximately 30.4 percent.

Cox is a veteran and Purdue University instructor. Baird, a farmer and Vietnam veteran, has represented the district since 2019.

The geography presents Cox with a serious problem. The district includes Lafayette and Purdue University but stretches across a broad swath of western and west-central Indiana containing numerous reliably Republican communities.

Baird therefore enters November with a substantial structural advantage.

Money illustrates the disparity. Reports through June 30 compiled by The Green Papers showed approximately $358,000 in receipts for Baird compared with about $20,000 for Cox.

Independent write-in candidate David Bokash has also declared for the general election.

The November race nevertheless gives voters a choice between Baird's established conservative record and Cox's effort to persuade the district that a different type of representation is warranted.

District 5: Victoria Spartz vs. J.D. Ford

This may be Indiana's most politically intriguing race outside District 1.

Republican Victoria Spartz is seeking a fourth term against Democratic state Sen. J.D. Ford.

Spartz has never been a conventional member of Congress. Born in Ukraine, she has developed a reputation for independence, confrontation and occasional criticism of her own party's leadership. Her priorities have included the national debt, health care and energy.

Ford offers Democrats an experienced state legislator rather than a first-time candidate. He has represented Senate District 29 since 2018 and has emphasized affordability, health care and government reform in his congressional campaign.

The district covers Delaware, Grant, Hamilton, Howard, Madison and Tipton counties, creating an unusual political mix.

Hamilton County remains enormously important. Its affluent suburbs have grown rapidly, and their political evolution has attracted attention for several election cycles. Republicans remain strong, but Democrats see suburban voters there as a potential source of future growth.

Ford therefore has a more plausible geographic argument than Democratic candidates in several of Indiana's overwhelmingly rural Republican districts.

The money is also more substantial here. Through June 30, Spartz had reported roughly $1.33 million in receipts, while Ford had reported about $582,000.

Spartz remains favored by the district's underlying Republican tendencies, but this is one race where HE will be watching the margins closely.

District 6: Jefferson Shreve vs. Cynthia Wirth

Republican Congressman Jefferson Shreve faces Democrat Cynthia "Cinde" Wirth in Indiana's 6th District.

Shreve's most revealing battle may already have occurred.

He faced Republican Sarah Brown in the May primary and survived what Indiana Capital Chronicle described as a close contest, demonstrating that even an incumbent Republican can face pressure from within the GOP in a strongly Republican district.

The district stretches through central and eastern Indiana and includes Johnson and Wayne counties as well as the southern portion of Marion County.

Wirth now gets the opportunity to make the Democratic case in November, but she confronts a district drawn with a substantial Republican advantage.

The question here may be less whether Democrats can flip the district than whether Shreve's difficult primary exposed any weakness that carries into the general election.

District 7: André Carson Defends Indianapolis

Indiana's political map changes dramatically when it reaches Indianapolis.

Democratic Congressman André Carson survived a competitive four-way Democratic primary and will face Republican Patrick McAuley and Libertarian James Sceniak in November.

Carson has represented the Indianapolis-based district since 2008 and won reelection in 2024 with 68.3 percent of the vote.

The greater drama came during the Democratic primary, when Carson faced challenges from Destiny Wells, George Hornedo and Denise Paul Hatch. Carson prevailed, demonstrating that Democratic voters were not yet prepared to replace him despite arguments from challengers that Indianapolis needed new representation.

Republicans will now try to accomplish in November what Carson's Democratic challengers could not accomplish in May.

The mathematics remain extremely difficult.

District 7 is contained entirely within Marion County and includes most of Indianapolis. For McAuley, a victory would require a political earthquake rather than a routine Republican turnout advantage.

Still, the results will offer an interesting measure of whether Republicans are making any meaningful progress with urban Indianapolis voters.

District 8: Mark Messmer vs. Mary Allen

Southwestern Indiana's 8th District features Republican incumbent Mark Messmer against Democrat Mary Allen. Independent James Burke has also declared a general-election candidacy.

Messmer entered Congress after winning the seat in 2024 and now seeks his first reelection.

The district encompasses much of southwestern Indiana, an area that once sent conservative Democrats to Washington but has moved dramatically toward Republicans over the past generation.

That political realignment is one of the larger stories behind Indiana's present congressional map.

For Allen, the challenge isn't simply defeating Messmer. Democrats must rebuild credibility in communities that once routinely elected members of their party but now vote Republican by substantial margins.

That makes District 8 an important measuring stick even if it doesn't become a nationally competitive race.

If Democrats eventually hope to rebuild a statewide coalition in Indiana, southwestern Indiana is one place where they will have to demonstrate that they can once again communicate with rural and working-class voters.

District 9: Erin Houchin vs. Brad Meyer — With More Choices on the Ballot

Southern Indiana's 9th District gives Republican incumbent Erin Houchin a reelection contest against Democrat Brad Meyer and Libertarian Tonya Hudson. Independent Floyd Taylor is running as a write-in candidate.

Houchin enters the fall with an enormous financial advantage.

Through June 30, her campaign reported approximately $1.86 million in receipts, compared with roughly $106,000 for Meyer. Hudson reported less than $2,000.

That difference doesn't guarantee an election result, but it demonstrates the scale of Meyer's challenge.

District 9 covers a large portion of southern Indiana, territory where Republicans have become exceptionally strong. Houchin first won the seat in 2022 and has now established the fundraising and organizational advantages that normally accompany incumbency.

Meyer must therefore find a way to turn a race Republicans expect to win into one voters believe is worth reconsidering.

Seven Races, But Not Seven Toss-Ups

Indiana's congressional map tells an unmistakable political story.

Republicans hold seven seats. Democrats hold two. That same 7-2 division has persisted since 2012.

The November election will test whether that arrangement has become Indiana's durable congressional equilibrium.

District 1 presents Republicans with their clearest opportunity to change it. District 5 offers Democrats an experienced state legislator challenging an incumbent whose unconventional political style has periodically produced controversy. District 7 remains the Democratic fortress centered on Indianapolis.

Across Districts 4, 6, 8 and 9, Democrats face much steeper climbs.

But congressional elections aren't merely about predicting winners. The margins matter. Turnout matters. County-by-county changes matter. And a district that moves five or ten points in one election can become tomorrow's battleground.

There is another reason to watch.

Control of the U.S. House will be determined nationally on November 3, with all 435 voting seats up for election. Indiana may not contain a half-dozen national toss-ups, but every seat ultimately contributes to the number that determines which party controls the House, chooses the Speaker and controls congressional committees.

For Hoosier voters, the choice is therefore both local and national.

Frank Mrvan, Jim Baird, Victoria Spartz, Jefferson Shreve, André Carson, Mark Messmer and Erin Houchin are asking Indiana voters to send them back to Washington. Their challengers are asking Hoosiers to send someone different.

On Tuesday, November 3, Indiana decides.
