Huh)2026-03-17T04:00:47Z CHICAGO (AP) Illinois voters are deciding primaries Tuesday for six open U.S. House and Senate seats that will spur a new generation of leadership in the states heavily Democratic congressional delegation.The retirement of longtime Sen. Dick Durbin, a Democrat, has triggered a competitive campaign, drawing as candidates two sitting House members and the lieutenant governor, among others. Sharp elbows and furious fundraising have marked the race, which also is a test of the influence of Democratic Gov. JB Pritzker, a billionaire whose name is floated as a 2028 presidential contender.A spate of House retirements has led to open seats with crowded contests across the Chicago area. The stakes are high, with most primary winners in the Democratic stronghold expected to win in November. The American Israel Public Affairs Committee and PACs supporting the cryptocurrency and AI industries also have spent big on several of the contests. Heres a look at the key races: 3 top Democrats running to replace DurbinTen Democrats and six Republicans are running after Durbin, the Senates No. 2 Democrat, announced his retirement after five terms.Three top Democrats have emerged: Chicago-area U.S. Reps. Raja Krishnamoorthi and Robin Kelly and Lt. Gov. Juliana Stratton.Krishnamoorthi has dominated fundraising and the airwaves and was the first on television with ads in July. He started 2026 with over $15 million on hand after spending more than $6 million and raising more than $3.5 million in the final three months of last year, according to campaign finance records. By comparison, Stratton started the year with $1 million after raising about the same amount and spending just under $1 million in the last three months of 2025. But last month Pritzker put $5 million in a super PAC largely aimed at helping get her elected. She campaigned on Pritzkers endorsement and lit into Krishnamoorthi at debates, particularly on the five-term Democrats voting record and donations from a contractor tied to U.S. Immigration and Customs Enforcement. That is not the example of somebody whos going to stand up to Donald Trump and fight for all of our communities, Stratton said during a debate in January. I want to abolish ICE.Krishnamoorthi, who has called to dismantle the agency, said he donated the money to immigrant rights groups. He argued that Stratton zeroed in on him because she didnt have any policy ideas. She had to attack.Meanwhile Kelly has taken issue with Pritzkers involvement, arguing that a sitting governor should not interfere.Candidates have touted ties to iconic Chicagoans including President Barack Obama and the late Rev. Jesse Jackson, who died last month. However, an endorsement touted posthumously by Stratton caused a snag as Jacksons family withdrew it Monday, saying the draft wasnt meant for public release. Election officials hope to see busy polls after turnout in the 2024 primary was 19%, the lowest in more than five decades. Roosevelt Jones, 67, said his Social Security and public safety were at the forefront as he cast an early ballot for Stratton in Chicago recently. She seems to be the one to take care of things, he said. In the Republican primary, six candidates are on the ballot including Don Tracy, former Illinois Republican Party chairman, and attorney Jeannie Evans. Illinois last had a Republican in the Senate a decade ago, when Mark Kirk was defeated by current Democratic Sen. Tammy Duckworth. Crowded US House primariesDozens of candidates are running for five open seats in the Chicago area where funding from groups supporting Israel and the cryptocurrency industry have played an outsized role.Ten Democrats and one Republican are running in Kellys district, the 2nd, which spans parts of the South Side and suburbs and dips into the central Illinois farmlands. Among the Democrats are former U.S. Rep. Jesse Jackson Jr., son of the late civil rights leader, Cook County Commissioner Donna Miller and state Sen. Robert Peters.The open seat in Krishnamoorthis suburban 8th District has attracted eight Democratic candidates including former U.S. Rep. Melissa Bean and Cook County Commissioner Kevin Morrison. Two other House members are retiring after long careers.The 7th District of Rep. Danny Davis, who was first elected in 1996, covers parts of downtown, the West Side and suburbs. Democratic front-runners to replace him include state Rep. La Shawn Ford, City Treasurer Melissa Conyears-Ervin, developer Jason Friedman and Kina Collins, a community organizer. Two Republicans are running.Rep. Jan Schakowsky is also retiring, after 14 terms, and the primary field for her 9th District seat is the most crowded. Among the 15 Democratic candidates are Evanston Mayor Daniel Biss, digital creator Kat Abughazaleh and state Sen. Laura Fine. Four Republicans are running.Another open seat is that of Rep. Jesus Chuy Garcia, who announced he would not seek reelection citing health reasons. The primary is uncontested after Garcia quietly schemed to place his chief of staff, Patty Garcia, who is not related to the congressman, on the ballot before a critical deadline. The move assured that no other Democrat would have time to circulate petitions. Then he withdrew. Pritzker seeking a third term as governorPritzker, an heir to the Hyatt Hotel fortune who is unopposed in his primary, is the first governor to seek a third term since the 1980s.One of President Donald Trumps most vocal critics, Pritzker used a campaign ad this month to highlight efforts to oppose the aggressive federal immigration crackdown in Chicago last year.I will always stand up for the law and the constitution, he said. Because thats what we do in the state of Illinois.Pritzker has also made digs at Republican candidate Darren Bailey, a former state senator whom he handily defeated in 2022.Bailey, among four Republicans vying for the nomination, says he is doing things differently. For one, he focused more on Chicago voters by choosing running mate Aaron Del Mar, who leads the Republican Party in Cook County. Bailey has criticized Pritzkers leadership, including blaming him for rising costs. Hes just another billionaire who has never once felt the pain hes inflicted, he said.Also in the Republican primary are Ted Dabrowski, a real estate developer; Rick Heidner, a video gambling magnate; and DuPage County Sheriff James Mendrick.
