Overview
Trafalgar Group is an American opinion-polling and survey company founded by Robert Cahaly and based in Atlanta, Georgia. It first released polling publicly in 2016, during the United States presidential election. The firm became prominent after publishing unusually favorable results for Donald Trump in several battleground states, including Michigan, where it was identified as the only pollster showing Trump ahead. It also came close to predicting Trump's victory in Pennsylvania and, according to contemporary assessments, correctly projected the overall electoral-vote result even though it did not identify every state that produced that outcome. The company presents itself as a polling operation designed to detect forms of response distortion that it describes as social-desirability bias. In addition to asking respondents how they intend to vote, Trafalgar has asked how respondents believe their neighbors will vote. The firm has said that this approach is intended to identify voters who may be reluctant to disclose their preferences directly. Its polling operation has used multiple contact channels, including live telephone calls, interactive voice response calls, text messages, online opt-in platforms, and two proprietary methods. The company generally uses short questionnaires, reportedly limited to nine questions or fewer, and works from a contact pool of approximately 75,000 potential respondents. It contacts members of that pool until it reaches a target sample size and researches characteristics such as voting likelihood. Trafalgar has stated that it applies relatively little weighting to its results. Unlike many major polling organizations, Trafalgar has concentrated on state-level presidential polling rather than national surveys. Cahaly has argued that the national popular vote is not the relevant statistic for determining the presidency. This focus, together with the firm's willingness to publish results that diverged sharply from polling averages, helped establish Trafalgar as a prominent outlier in American election coverage. Trafalgar's record has been mixed. Its 2016 polling successes made it influential among analysts and conservative political audiences. In the 2020 presidential election, FiveThirtyEight calculated that Trafalgar's average statistical error was approximately 2.6 percentage points, better than the average error across pollsters that year. However, the firm predicted that Trump would win the national election and several states that Joe Biden ultimately carried, including Arizona, Georgia, Michigan, Nevada, and Pennsylvania. Its polling for the 2021 Georgia Senate runoffs and that year's Virginia gubernatorial election produced some relatively close or accurate estimates, although it missed the eventual outcome in the Georgia contest involving Kelly Loeffler and Raphael Warnock. The firm's 2022 midterm polling was substantially less successful. Trafalgar projected Republican victories or competitive races in a number of states where Republican candidates ultimately lost by clear margins. These included races involving Mehmet Oz, Herschel Walker, Kari Lake, Tudor Dixon, Adam Laxalt, Blake Masters, Christine Drazan, and Tim Michels. It also portrayed several other Republican candidates as being within striking distance when some, including Doug Mastriano, lost decisively. Trafalgar has faced sustained criticism over transparency and partisan skew. Conventional pollsters and election analysts have questioned the firm's sampling design, its use of fixed contact pools, its treatment of low-engagement voters, and its limited public disclosure of methodological details. FiveThirtyEight has found that Trafalgar generally overestimated Republican performance by about two points. The firm has defended its privacy around proprietary techniques, with Cahaly arguing that the methodology should be evaluated by its results rather than fully disclosed. Its reputation therefore combines innovation and occasional forecasting success with controversy over reproducibility, transparency, and a perceived Republican lean.
History
Trafalgar Group was founded by Robert Cahaly and is based in Atlanta, Georgia. The company first entered public view as an election-polling organization in 2016. Its early public identity was shaped by a willingness to publish findings that differed sharply from the polling consensus, particularly in the U.S. presidential election. Trafalgar was the only cited polling firm showing Donald Trump ahead in Michigan and was regarded as nearly alone in correctly indicating a Trump victory in Pennsylvania. The firm also reportedly matched the eventual electoral-vote total for the two candidates, although it did not correctly identify every state contributing to that total. The company's approach relies on a mixture of conventional and proprietary voter-contact methods. These include live telephone interviews, interactive voice response calls, text messages, online opt-in recruitment, and two additional methods that Trafalgar treats as proprietary. Rather than relying exclusively on open or broadly distributed sampling, it has used a recurring contact pool of roughly 75,000 potential respondents. The firm researches people in that pool for characteristics such as likely turnout and contacts respondents until it obtains a target sample. Questionnaires are generally short, commonly consisting of no more than nine questions. Trafalgar has said that it applies limited weighting to its results. A defining feature of the firm's methodology is its effort to account for what it calls social-desirability bias. Trafalgar argues that some respondents may be unwilling to tell a pollster their actual voting preference, particularly when they believe the preference may be socially disfavored. Its surveys have therefore asked both how respondents intend to vote and how they think their neighbors will vote. The company has also described the use of lifestyle and engagement data to locate voters who might otherwise be missed by traditional approaches. In presidential elections, Trafalgar has generally emphasized state-level polling rather than national surveys, arguing that the national popular vote is not what determines the presidency. Trafalgar remained an outlier in later election cycles. In Georgia's 2018 gubernatorial race, its final poll showed Brian Kemp with a 12-point advantage even though most other polls showed a much closer contest. Kemp won, but by less than two points. Before the 2020 presidential election, Trafalgar predicted a Trump victory and projected Trump wins in Arizona, Florida, Georgia, Michigan, Nevada, North Carolina, and Pennsylvania. FiveThirtyEight later calculated that Trafalgar's average error was about 2.6 points, better than the average error among pollsters in that unusually difficult cycle. Nevertheless, the firm missed the winning candidate in several battleground states, limiting the value of its overall election call. The 2021 Georgia Senate runoffs produced another mixed result. Trafalgar initially showed Republican incumbents Kelly Loeffler and David Perdue ahead, then later showed both trailing. Its final pre-election forecast reversed those movements by predicting narrow leads for Loeffler and Perdue. Jon Ossoff defeated Perdue, while Raphael Warnock defeated Loeffler. In the 2021 gubernatorial contests, Trafalgar's Virginia poll closely approximated Glenn Youngkin's narrow victory, while its New Jersey poll correctly projected a Phil Murphy win but overstated his final margin. Trafalgar's standing deteriorated after the 2022 midterm elections. It projected Republican wins or close races in numerous contests that Republicans ultimately lost, including races involving Mehmet Oz, Herschel Walker, Kari Lake, Tudor Dixon, Adam Laxalt, Blake Masters, Christine Drazan, and Tim Michels. It also characterized several other Republican campaigns as competitive when some candidates, including Doug Mastriano, lost by large margins. The firm has faced continuing criticism because it does not fully explain its sampling and weighting procedures. The New York Times and other commentators have described the available methodology as insufficiently specific, while FiveThirtyEight has reported that Trafalgar generally overestimates Republican performance by approximately two points. Trafalgar has defended its decision to keep parts of its process private, arguing that its proprietary techniques should be judged by performance. FiveThirtyEight's ratings have fluctuated considerably, from C-minus before the 2020 election to A-minus afterward, then B in March 2023, and 0.7 out of 3 in September 2024. These changes reflect the firm's uneven record and the difficulty of evaluating a pollster whose methods are not fully reproducible from public documentation.
