Senate Race — Ron Johnson (R) Defending
Johnson: Three-Term Senator With a Vulnerability Problem
Ron Johnson has survived two consecutive close elections — making Wisconsin Democrats' top Senate pickup target in 2026 — winning in 2016 by 3.4 points and in 2022 by 1.3 points — despite consistently low approval ratings. Heading into 2026, he faces what may be his toughest environment yet: a midterm election with Trump in the White House — reflected in the Trump approval rating — an organizational Democratic infrastructure that has competed hard in Wisconsin for a decade, an organizational Democratic infrastructure that has competed hard in Wisconsin for a decade, and his own approval ratings that have rarely crested 40%.
Johnson has been a vocal ally of Trump and has taken positions on Social Security, Medicare, and elections that Democrats have used effectively against him in prior cycles. In 2022, Democrats ran Mandela Barnes — a candidate with weaknesses of his own — and still came within 1.3 points. A stronger Democratic nominee in 2026, in a better national environment, makes this race a genuine toss-up.
Governor Race — Tony Evers (D) Seeking Third Term
Governor Tony Evers has won two consecutive close elections in Wisconsin — defeating Scott Walker in 2018 by 1.1 points and winning re-election in 2022 by 3.4 points. The 2022 margin, won the same night Johnson narrowly survived, suggested that Evers had built a durable personal brand that allowed him to run ahead of the Democratic baseline. His third-term bid is rated Lean D, reflecting both his incumbency advantage and the midterm environment favorable to Democrats.
Evers has positioned himself as a pragmatic center-left governor, frequently clashing with the Republican-controlled legislature but maintaining approval ratings in the mid-to-high 40s. Republicans will need to recruit a strong candidate — likely from the legislature or the business community — to have a serious shot at the governorship while simultaneously defending the Johnson Senate seat.
Key Voter Groups — Wisconsin
Milwaukee County is the engine of Democratic turnout in Wisconsin. High turnout among Black voters is essential for Democrats to win statewide. In 2022, Barnes underperformed in Milwaukee, contributing to his narrow loss. A strong Milwaukee performance is non-negotiable for any Democratic Senate candidate.
Dane County (Madison) returns some of the highest Democratic margins in any large metro area. Turnout among University of Wisconsin students and young college-educated professionals is a key variable. Dane County alone can deliver 70,000+ Democratic margin votes in a strong cycle.
The Fox Valley (Appleton, Oshkosh, Green Bay) represents the critical persuadable working-class voters who once formed the backbone of Wisconsin Democrats. Many shifted to Trump in 2016 and have not returned. Democratic candidates who can limit their losses here outperform their statewide average.
Waukesha, Ozaukee, and Washington counties (WOW) in suburban Milwaukee have trended toward Democrats among college-educated suburbanites but remain Republican-leaning overall. A structural shift here — even a few points — could be decisive in a sub-one-point race.
Race Analysis
Maximize Milwaukee and Dane County turnout. Recruit a strong candidate who avoids Barnes’ weaknesses. Benefit from a 4-6 point midterm tailwind against the Trump White House. Run on Johnson’s Social Security and Medicare positions to peel off senior voters in Fox Valley and Green Bay.
Johnson runs on Trump’s economic record and ties the Democratic nominee to unpopular national party figures. Rural and Fox Valley turnout stays high. Democrats nominate a flawed or ideologically polarizing candidate. Johnson’s personal brand as an independent-minded senator resonates in final weeks.
The quality of the Democratic nominee. In 2022, Barnes gave Johnson room to define the race on crime and culture. A credentialed, moderate Democrat who frames the race on economic security and Johnson’s votes against popular programs could flip this seat. The candidate matters more here than in almost any other race.
