Indiana Democrats Break Republican Supermajority in Statehouse Election Results

Indiana Democrats won 15 House seats Tuesday, ending the Republican supermajority that had dominated the statehouse for over a decade. The shift gives the minority party more influence over committee assignments, policy discussions, and the ability to override a governor’s veto—previously an automatic Republican advantage, according to WFYI. Republicans still hold majority control in both chambers, but they can no longer act alone on major decisions, and Democrats will now sit on more committees with real influence over which bills advance.

The shift came as voters also delivered two statewide offices to Democrats and unseated long-serving Republican incumbents, including House Speaker Todd Huston, who conceded Wednesday to Democrat Lauren Cole in Hamilton County. Republicans had held a House supermajority since 2012 and a Senate supermajority since 2010, making Tuesday’s results a break in the House supermajority that had lasted over a decade.

What the supermajority loss actually changes

A supermajority—more than two-thirds of seats in a chamber—let Republicans override gubernatorial vetoes without a single Democratic vote. That power is gone in the House. Democrats’ 15-seat gain also means more members on committees, where bills live or die before reaching the floor.

House Minority Leader Phil GiaQuinta (D-Fort Wayne), reelected as House leader Wednesday alongside Rep. Cherrish Pryor (D-Indianapolis) as minority floor leader and Rep. Carey Hamilton (D-Indianapolis) as minority caucus chair, said his caucus expects to be taken seriously now.

“We pride ourselves on being pragmatic problem solvers, so we’re going to work and reach across the aisle where we can, and we try to take on serious issues and find solutions to those problems,” GiaQuinta said.

Republicans scrambled Wednesday to install new leadership after Huston’s loss, nominating Rep. Ben Smaltz (R-Auburn) as the new Speaker. Smaltz, a chief architect of last year’s redistricting push, told reporters Republicans would focus on affordability and said revisiting redistricting was unlikely. Rep. Matt Lehmen (R-Berne) was named House Majority Leader and Rep. Jake Teshka (R-North Liberty) Majority Caucus Chair.

The Democratic gains toppled some of the chamber’s most senior figures. Rep. Bob Behning (R-Indianapolis), a leader in state education policy since 1992, lost his seat. Rep. Ed Soliday (R-Valparaiso), who served 20 years, was unseated by Democrat Ryan Kominakis. Huston, in his concession, blamed national headwinds.

“This was an incredibly challenging midterm election, and ultimately the national headwinds were too difficult to overcome in a number of our races,” Huston said. “It’s been the honor of my life serving Hoosiers in Hamilton County and across our great state.”

Indiana University Indianapolis political science professor Aaron Dusso attributed the Democratic surge to a national wave: President Donald Trump’s low approval numbers, the war with Iran, and voter concerns about affordability created what he called a “perfect storm.”

“In a lot of ways, it’s a rising tide raises all ships kind of situation,” Dusso said.

Indiana Public Radio added that the Democratic Legislative Campaign Committee had targeted six Indiana House races back in May, and that the gains came after Indiana Republican lawmakers failed Trump’s demand that they redraw congressional districts to favor the GOP—a refusal that preceded a national push to strengthen Democratic statehouse candidates.

Republicans secure Senate leadership roles

The Senate also lost Republican seats, though Republicans appear to have kept their majority there. Republicans moved forward with Sen. Chris Garten (R-Charlestown) as their choice for Senate President Pro Tem, a post he sought after Rodric Bray stepped aside; Bray’s departure followed a Republican primary in which several Trump opponents, including Bray himself, were ousted. Garten announced Sen. Eric Koch (R-Bedford) as Majority Floor Leader. Garten’s own race remained uncalled Wednesday night, with a roughly 300-vote lead over Democrat Nick Marshall, who said he was still tracking down remaining votes before deciding whether to concede.

Beyond the Statehouse, Democrat Beau Bayh declared victory in the Secretary of State race Tuesday, and Jessica Bailey announced victory in the Comptroller race Wednesday—two statewide offices flipping to Democrats on the same night.

Legislators stress proving momentum

GiaQuinta did not lay out specific bills Wednesday but said his caucus’s focus would remain on affordability. Dusso cautioned that Democrats now face the work of proving the momentum can last, especially with the 2028 election ahead.

“The reality is that they need to build on this in a way that they can, make a public show, essentially show to Indiana and Hoosier voters that they can do something and that they have an agenda that people could get behind,” Dusso said.

The ceremonial start of the 2027 legislative session, Organization Day, is set for Nov. 17, when the new balance of power will first be on public display.
