Wisconsin House Voting Record 2026: Public-Roll-Call Signals and Source-Readiness for Incumbent Research

H2: What Public Voting Records Exist for Wisconsin House Incumbents

Public voting records for Wisconsin House incumbents are primarily drawn from the official congressional roll-call database maintained by the Clerk of the House, supplemented by state legislative records for incumbents who previously served in the Wisconsin State Assembly or Senate. Researchers examining the 2026 Wisconsin House field would start with the publicly available vote summaries on Congress.gov, which provide a complete record of every roll-call vote cast by each incumbent since they entered office. These records include vote totals, party-line breakdowns, and individual member positions on each bill, amendment, or procedural motion. For incumbents with prior state legislative experience, the Wisconsin Legislative Reference Bureau offers searchable databases of floor votes and committee actions, though the depth of coverage varies depending on the year and chamber. OppIntell's platform aggregates these public sources into structured, source-backed profile signals, allowing campaigns to assess what any opponent or outside group could surface from open records. In the current 2026 research universe, Wisconsin accounts for 476 tracked candidates across four race categories, with an average of 71.15 source-backed claims per candidate, indicating a rich baseline of publicly verifiable information.

H2: Biographical and District Context for Key Wisconsin House Incumbents

The Wisconsin House delegation includes incumbents from both parties, each with distinct voting records shaped by their district's demographic and political composition. Among the most researched candidates in the state are Mark Pocan, Glenn S. Grothman, and Gwen S Moore, according to OppIntell's tracked candidate universe. Pocan, a Democrat representing the 2nd District covering Madison and surrounding Dane County, has a consistently progressive voting record on labor, healthcare, and environmental issues, with high party-unity scores. Grothman, a Republican from the 6th District in east-central Wisconsin, tends to vote along conservative lines on fiscal policy and social issues, often breaking with party leadership on spending bills. Moore, a Democrat from the 4th District encompassing Milwaukee, has a strong record on civil rights and urban development, frequently co-sponsoring legislation focused on economic equity. Each incumbent's voting record reflects and the electoral pressures of their district: Pocan's district is reliably Democratic, Grothman's leans Republican, and Moore's is a Democratic stronghold but with competitive primaries. Researchers would also note that Wisconsin's House seats are all currently held by incumbents, meaning the 2026 cycle may feature primary challenges or open-seat contests depending on retirements. The state-level party mix in OppIntell's tracking is 158 Republican, 283 Democratic, and 35 other candidates across all race categories, but for House races specifically, the incumbents are split 5 Republican and 3 Democratic, creating a balanced field for comparative voting record analysis.

H2: Party Comparison: How Republican and Democratic Voting Records Diverge

A party comparison of Wisconsin House voting records reveals clear ideological fault lines that researchers would examine in detail. Republican incumbents, such as Bryan Steil (1st District), Tom Tiffany (7th District), and Derrick Van Orden (3rd District), have generally supported tax cuts, deregulation, and increased defense spending, while opposing expansions of federal healthcare programs and climate change initiatives. Democratic incumbents, including Pocan, Moore, and Mark Pocan, have voted for the Inflation Reduction Act, the CHIPS and Science Act, and other Biden-era legislation, with near-unanimous party support on key votes. One notable divergence appears on agricultural policy: Wisconsin's rural districts (3rd, 6th, 7th) often see bipartisan votes on farm bills and dairy subsidies, but urban districts (2nd, 4th) produce more partisan splits on nutrition and environmental provisions. Researchers would also look at procedural votes, such as motions to recommit or rules packages, which can signal a member's willingness to work across the aisle or adhere to party discipline. For example, a Republican incumbent who frequently votes against the majority of their party on appropriations bills may be positioning themselves as a fiscal conservative independent of leadership, while a Democrat who breaks with the party on trade agreements may be responding to district-specific manufacturing concerns. OppIntell's source-backed profiles capture these nuances by tagging each claim with its public source, allowing campaigns to see exactly which votes a researcher would cite in an attack ad or debate question. The platform's data shows that Wisconsin candidates have a high source-readiness rate—476 of 476 tracked candidates have at least one source-backed claim—but the depth varies, with some incumbents having hundreds of roll-call votes documented and others relying more on statements or media coverage.

H2: Source-Readiness Gap Analysis: What Researchers Would Check Next

Source-readiness refers to the degree to which a candidate's public profile can be substantiated with verifiable, citable sources—in this case, official voting records. For Wisconsin House incumbents, the source-readiness is generally high because roll-call votes are permanently recorded and easily accessible. However, gaps exist in areas such as committee votes (which are sometimes recorded only form), votes on amendments that fail, and positions taken before entering Congress. Researchers would check whether an incumbent's voting record on a specific issue—say, healthcare or immigration—is consistent with their campaign rhetoric or past statements. For example, an incumbent who votes against a popular bipartisan bill but later claims to support its goals may face a credibility gap that opponents could exploit. Another gap involves votes that are not roll-call but voice votes or unanimous consent agreements, which are not individually recorded; these can obscure a member's position on less controversial matters. OppIntell's methodology flags these gaps by noting when a claim is based on a direct vote versus a statement or media report, giving campaigns a clearer picture of what evidence an opponent could actually produce. In the broader 2026 cycle, OppIntell tracks 21,970 candidates across 54 states, with 3,713 well-sourced (five or more claims) and 238 thinly-sourced (zero claims). Wisconsin's incumbents fall into the well-sourced category, but the quality of sourcing depends on the researcher's ability to connect specific votes to broader narratives—for instance, tying a series of environmental votes to a pattern of climate denial or support for green jobs.

H2: Competitive-Research Framing: How Campaigns Use Voting Record Intelligence

Campaigns in Wisconsin can use voting record research to anticipate what opponents and outside groups may say about them in paid media, earned media, or debate prep. The key is to identify which votes are most likely to be weaponized: high-profile bills with clear partisan divides, votes that contradict a member's stated values, or votes that affect a district's major industries. For Wisconsin, agriculture, manufacturing, and healthcare are salient issues, so a vote on the Farm Bill, the USMCA, or the Affordable Care Act amendments would be highly scrutinized. A campaign might preemptively prepare a response by framing the vote in district-specific terms—explaining why a 'no' vote on a climate bill actually protected local energy jobs, for example. OppIntell's platform enables this preparation by providing a structured, source-backed profile of each incumbent's voting record, including the exact roll-call number, date, bill title, and vote outcome. This allows a campaign to see not just what an opponent could say, but exactly what source they would cite. In a competitive primary or general election, the ability to control the narrative around a voting record can be decisive. For instance, a challenger might use an incumbent's vote against a popular local project to paint them as out of touch, while the incumbent's team could counter with a broader record of constituent service. The source-backing ensures that both sides are arguing from the same factual baseline, reducing the risk of misinformation. OppIntell's research universe shows that Wisconsin is one of the most tracked states, with 476 candidates and a high cross-platform verification rate (19 candidates verified across FEC, Wikidata, and Ballotpedia), meaning the data is robust enough for serious competitive analysis.

H2: Methodology for Comparative Voting Record Analysis

Comparative voting record analysis requires a systematic approach to selecting which votes to compare and how to weight them. Researchers would first define a set of key votes—often those identified by interest groups like the American Conservative Union or the liberal Americans for Democratic Action—and then compute each incumbent's agreement score with their party or with a specific ideological benchmark. For Wisconsin House incumbents, a researcher might compare the voting records of the two parties' members on a common set of bills, such as the 2023 debt ceiling agreement or the 2024 defense authorization. Another method is to analyze voting blocs within the state delegation, looking for coalitions that cross party lines on issues like Great Lakes funding or trade policy. OppIntell's platform supports this by tagging each vote with issue categories and allowing users to filter by party, district, or vote outcome. The platform also tracks changes over time, so a researcher could see if an incumbent's voting record has shifted left or right during their tenure—a signal of potential vulnerability in a primary. For example, a Republican incumbent who voted for the 2022 infrastructure bill might face a primary challenge from the right, while a Democrat who opposed the Green New Deal could draw a progressive challenger. The source-readiness of each claim ensures that these comparisons are grounded in verifiable data, not speculation. In Wisconsin, where the party mix is 158 Republican to 283 Democratic across all races, but House incumbents are evenly split, comparative analysis is particularly useful for identifying which districts are most likely to flip and what voting record patterns could drive that change.
