Simplistic Electoral Forecast [1]
Margin of Error
[ Methodological Framework & Error Caution ]
The Data Desert: Unlike top-ticket statewide races, Wisconsin state legislative races are notoriously difficult to poll. Because there is virtually zero high-quality public polling data for SD-21, this win probability forecast averages highly fragmented internal metrics and qualitative, anecdotal reports from ground organizers [1]. As a result, the Margin of Error is estimated at a massive ±11.5%. Do not mistake the 52/48 split for a definitive prediction; this overlap zone means the general election is a statistical toss-up.
General Election Dynamics: In a general election environment, predicting SD-21 (Racine/Kenosha) turnout requires accounting for Wisconsin's notorious ticket-splitting electorate. Local economic issues—like the Foxconn development zone and manufacturing revitalization—often encourage swing voters to break from top-of-the-ticket partisan loyalty [4].
Turnout Scenarios & Margins [2]
| Scenario | Est. Ballots Cast | Win Target Threshold | Electorate Composition |
|---|---|---|---|
| LOW TURNOUT | 55,000 | 27,501 | Base-Heavy / Midterm Drop-off |
| EXPECTED (BASE) | 70,000 | 35,001 | Standard Midterm Participation |
| HIGH TURNOUT | 85,000 | 42,501 | High Independent / Presidential-Level Surge |
Capital Allocation & Financials [3][5]
| Candidate | Win Prob. | Total Raised | Disbursements | Cash on Hand | Est. $/Voter |
|---|---|---|---|---|---|
| T. Jung (D) | 52% | $175,000 | $61,765 | $242,500 | $5.00 |
| J. Croft (R) | 48% | $123,000 | $38,000 | $85,000 | $3.51 |
Electoral Cartography: SE Wisconsin Topography [4]
Spatial Distribution & Field Zones
-
Racine Proper (RAC): High density of active voters and local municipal organizing. Jung (D) holds a measurable advantage in traditional city wards here.
-
Kenosha Corridors (KEN): The southern anchor of the district. Strong base for Croft (R) fueled by manufacturing revitalization messaging.
-
Mount Pleasant & I-94 (MTP): The swing region. Dominated by discussions over the Foxconn footprint and utility developments. Highly susceptible to general election ticket-splitting.
The Architecture of the Ground Game: WI SD-21

ith Wisconsin's partisan primary election taking place on Tuesday, August 11, 2026 (in 2 days) and the general election following on Tuesday, November 3, 2026 (in 86 days), the contest in Wisconsin's 21st State Senate District has tightened into a strict margin-of-error race. Spanning the critical lakeshore communities of Racine and Kenosha, and stretching west across the I-94 corridor, the race will test traditional organizing against regional economic appeals.
Based on anecdotal reports from campaign staff on the ground—and a highly simplified averaging of available contact metrics—Democrat Trevor Jung mathematically prints out a slight edge of a 52% to 48% probability of securing the election over Republican Jim Croft. However, that 4-point spread is entirely eclipsed by an estimated ±11.5% margin of error [1]. Because there is virtually no reliable public polling at this district level, treating these win probabilities as anything other than a complete toss-up is statistical malpractice.
Jung’s operation has heavily focused on Racine’s urban wards, pushing traditional canvassing strategies. Conversely, Croft has consolidated support further south in Kenosha while leaning into manufacturing and energy infrastructure messaging tailored to the industrial corridors [4].
The financial parity between the campaigns reflects the closeness of the race. Scaled for a general election environment, Trevor Jung raised $175,000 in the first half of the year with over $240,000 in cash on hand and $61,765 in disbursements, while Jim Croft raised $123,000 with approximately $85,000 in cash on hand and $38,000 in disbursements [3][5]. With an expected baseline turnout of 70,000, campaigns are effectively spending between $3.51 and $5.00 per target vote to secure the majority. Tuesday's result will ultimately hinge on which candidate can better motivate independent swing voters along the highway grid without alienating their core municipal base.
