Blue tsunami raises Democrats' already massive advantages in the Illinois General Assembly

Democrats’ nationwide blue tsunami swept through Springfield on Tuesday night, too, running up the state party's super majorities toward historic highs in the Illinois General Assembly.

While facing criticism from within his own caucus for his handling of sexual harassment allegations by a former member, House Speaker Emanuel “Chris” Welch’s political operation flexed its muscle to flip at least four districts on Election Day.

By Wednesday morning, three additional House seats were still in play for Democrats, potentially paving the way to a staggering 85-33 advantage for Welch’s party.

Democrats have held a 78-40 House advantage over Republicans under Welch’s leadership since 2022, already the largest in modern history on a starkly gerrymandered political map.

Illinois Senate President Don Harmon was poised to expand the hefty Democratic edge in the upper chamber as well, grabbing four new seats across the state and potentially two more that would increase their dominance to 46-13.

With Democratic blowouts in favor of Gov. JB Pritzker, Attorney General Kwame Raoul, Comptroller-elect Margaret Croke and all other statewide office-holders, Illinois Republicans find themselves in their bleakest position in recent memory.

Among the Democratic spoils was state Rep. Nabeela Syed’s victory over incumbent Republican state Sen. Darby Hills for the northwest suburban 26th Senate District seat, a $6.5 million contest that marked one of the most expensive in state history.

But Democrats were also making inroads in territory long considered solid Republican ground, including the Rockford seat held by GOP state Sen. Dave Syverson since 1993. Democratic challenger Sarah Mertens held a narrow edge with 85% of expected votes counted by Wednesday morning.

The Welch-controlled Democrats for the Illinois House political committee raised some $35 million to tighten its grip on the Capitol.

He’ll still face a battle to hold onto the speaker’s gavel in January, as several members of his caucus have begun organizing behind closed doors to name a new speaker in the wake of Welch’s handling of misconduct allegations leveled against former Plainfield state Rep. Harry Benton. Democrats still held onto that 97th District seat with the help of a $1.6 million infusion from Welch’s operation.

Welch called their big night across the board “a testament to the strength of our members, the dedication of our campaigns, and the voters who continue to place their trust in House Democrats.”

“We set out to protect our incumbents, expand our majority, and make sure members had the resources necessary to compete and win,” Welch said in a statement. “Our historic supermajority is not just a reflection of electoral success. It is a mandate to continue delivering meaningful results for the people of Illinois.”

“The people of Illinois expect us to govern, to lead, and to deliver,” Welch added. “We will continue doing exactly that. Our majority is stronger, our caucus is growing, and our commitment to building a better Illinois has never been greater.”

Illinois Senate President Don Harmon said they reached "an overwhelming victory for Democrats because we've been focused on what matters to voters. We've fought to lower costs, improve healthcare, and stop the Trump administration in its tracks. We're excited to get back to work on behalf of the people with our new majority."

Political funds controlled by Harmon carried more than $32 million into the home stretch of the campaign season, dwarfing Republican war chests that have shrunk over the past decade with the exodus of conservative megadonors like Ken Griffin and Dick Uihlein.

The Illinois GOP has withered due largely to President Donald Trump’s deep unpopularity in suburban areas that long provided the lifeblood of the state party.

But members of the hardline conservative Illinois Freedom Caucus, the fiercest Trump supporters in the General Assembly, suggested their party should respond to the bloodbath by leaning toward their pole.

“How much worse does it need to get before we try something new?” members of the downstate caucus said in a statement. “We are ready to unite as Republicans and look to the future, but we cannot ignore failure. Tonight was an absolute disaster. The 2028 election starts now. We look forward to hearing from our colleagues about their ideas for the future, because the only way to influence change is by winning elections.”
