New York's 9th congressional district

Evanston's City Council appointed 4th Ward Ald. Jonathan Nieuwsma as acting mayor following Daniel Biss' resignation, as Biss is heavily favored to win Illinois' 9th Congressional District seat in the Nov. 3 election. Council members chose Nieuwsma in a 5-4 vote that followed several failed attempts to nominate other aldermen, most of whom declined consideration. Nieuwsma, who has served as alderman since 2021, is not among the six candidates running in the Feb. 23 mayoral primary and plans to remain 4th Ward alderman after that race concludes. He will serve as acting mayor until April 2027, when voters elect someone to complete Biss' term, which runs through May 2029.

With Election Day a week away, Illinois Democrats are campaigning beyond state lines to aid party allies nationally. Rep. Raja Krishnamoorthi backed Texas Railroad Commissioner candidate Jon Rosenthal; Sen. Tammy Duckworth campaigned for Sherrod Brown in Ohio; Rahm Emanuel canvassed in New Hampshire; and Rep. Danny Davis and successor nominee La Shawn Ford campaigned for Wisconsin gubernatorial candidate David Crowley. Gov. JB Pritzker is focused on his own reelection, holding a large cash advantage and backing fellow Democrats financially.

Big money is also flowing into Illinois races, including Chicago school board contests, with GOP megadonors Dick and Elizabeth Uihlein and wealthy Democratic-aligned groups both spending heavily to shape outcomes from Springfield to Chicago.

Onondaga County, N.Y., voters head to the polls in November to decide control of the County Legislature for the first time under newly lengthened four-year terms, with candidates running in all 17 districts. Democrats, who won a historic 10-7 majority in 2025, are seeking a veto-proof 12-seat supermajority that would let them bypass Republican County Executive Ryan McMahon, who has vetoed several Democratic measures this year, including a term-limits bill now headed to voters. Republicans, boosted by heavy fundraising from county contractors, aim to reclaim at least a nine-seat majority. Key swing districts include the 2nd, 6th, 11th, and 14th. Both parties are investing heavily, with turnout and lingering reaction to President Trump seen as pivotal factors.

Shelby County, Tennessee's largest voting jurisdiction with more than 582,000 registered voters, heads into the November midterms under a new congressional map after the Republican-led legislature redrew districts in May, splitting the state's only Democratic-held seat, centered on majority-Black Memphis, into three districts: 9, 8, and 5. Republicans currently hold eight of Tennessee's nine congressional seats and hope redistricting helps them sweep all three Shelby County races. Early voting begins October 14.

District 9 pits Republican Brent Taylor against Democrat Justin Pearson, alongside independents. District 8 features Republican incumbent David Kustoff against Democrat Heidi Kuhn and several independents, while District 5 has Republican Charlie Hatcher facing Democrat Chaz Molder. Local political observers view District 5 as potentially the most competitive race, while some believe Pearson has a viable shot in District 9. Election officials say they've added review processes after a ballot error affected roughly 700 absentee voters in July, and expect the redistricting fight could drive higher turnout among voters upset by the changes.

Florida's primaries produced a mixed picture for both parties ahead of November's general election. Rep. Byron Donalds won the Republican gubernatorial nomination with Trump's endorsement and a large financial edge, beating Lt. Gov. Jay Collins, former House Speaker Paul Renner and newcomer James Fishback despite Gov. Ron DeSantis's public misgivings; Donalds would become Florida's first Black governor if elected. Former Republican congressman David Jolly, running with Gwen Graham as his lieutenant governor pick, won the Democratic nomination over state Rep. Dotie Joseph and others, pitching himself as a centrist who wants to end the culture wars. The two will meet in November to succeed the term-limited DeSantis, in a state where Democrats haven't won the governorship in over 30 years.

Progressive state Rep. Angie Nixon defeated establishment-backed Alex Vindman for the Senate Democratic nomination despite being outspent; she faces Republican Sen. Ashley Moody, who won her primary with Trump's backing, in the special election for Marco Rubio's former seat. Incumbents Debbie Wasserman Schultz and Jared Moskowitz turned back challengers, including Sheila Cherfilus-McCormick, in redrawn districts under Florida's new Republican-favored congressional map. Trump-endorsed Cory Mills lost his House primary amid domestic violence allegations, while far-right figures Dan Bilzerian and Madison Cawthorn were also defeated, alongside Rep. Randy Fine's contentious win.
