Rasmussen first became known for his public opinion polling work. In the 1990s, he was a leader of the
term limits movement. He continues to conduct polls for
U.S. Term Limits. In 1995, he founded a polling company called GrassRoots Research. In the
Wall Street Journal, political journalist
John Fund called him "America's insurgent pollster".
Susan Estrich, the first female campaign manager of a major presidential campaign, said of him, "If you really want to know what people in America think, you can't find a smarter guy to ask than Scott Rasmussen." Rasmussen has described himself as "an independent pollster" who "[l]ike the company he started, [...] maintains his independence and has never been a campaign pollster or consultant for candidates seeking office." In 2010, some Democrats criticized Rasmussen's polling methodology. Democratic pollster Mark Mellman said Rasmussen Reports polls "tend to be among the worst polls for Democrats." Tom Jensen, a pollster for Democratic firm
Public Policy Polling said: "The way [Rasmussen] does polls is that he's more likely to get high-energy voters. I think Rasmussen favors Republicans this year, but I don't think he inherently favors Republicans." In August 2018, Rasmussen released a public opinion website, ScottRasmussen.com, in conjunction with the announcement of a partnership between ScottRasmussen.com and HarrisX, an online research company under The Stagwell Group, which was founded by former pollster and adviser to
President Bill Clinton,
Mark Penn. Former U.S. House Speaker
Newt Gingrich said that "Scott Rasmussen has done America an enormous service. He identified the driving forces behind the destructive radicalism which is pushing us into a cultural civil war."
Napolitan Institute Rasmussen founded the
Napolitan Institute in 2024. Through the Napolitan Institute and RMG Research, Rasmussen conducts polling focused on the "Elite One Percent" and federal government managers. Rasmussen's surveys of federal government managers revealed that a significant number of federal employees would not obey a legal order from President Trump. In July 2025, the Napolitan Institute announced an
AI-based partnership with
Jigsaw, a technology incubator created by
Google. The partnership will involve convening online conversations with Americans from every congressional district and presenting the public opinion gleaned from these conversations in a July 2026 commemoration of the
United States Semiquincentennial.
Rasmussen Reports In 2003, Rasmussen founded Rasmussen Reports, LLC, a U.S.-based public opinion polling company, to track consumer confidence, investor confidence, and presidential approval. Rasmussen Reports has been called "one of the most consistently interesting polling and analytics companies," generating a daily cycle of news reports based on original survey results as well as political, business, economic and lifestyle content. Unlike traditional pollsters whose polls are often influenced by partisanship, the company's business model relies on website advertising and paid subscriptions for premium content. Rasmussen Reports' polls were notable for their use of automated public opinion polling, involving pre-recorded telephone inquiries, which have been shown to produce accurate results at low cost. In 2009, Noson Lawen Partners provided a significant investment in Rasmussen Reports. In 2010, Rasmussen Reports was one of two firms providing daily tracking updates of the president's job approval ratings as well as consumer confidence. By 2012, Rasmussen Reports had garnered a national reputation for providing "reliable, newsworthy and actionable public opinion data," receiving over one million visits per day during the presidential election that year. In a press release from Rasmussen Reports, the company confirmed Rasmussen's departure and said, "[i]n part, the move reflects disagreements over company business strategies .... The Company emphasized that Mr. Rasmussen's legacy remains intact. His polling methodologies and protocols, widely acknowledged as among the most accurate and reliable in the industry, continue to guide and inform the company's public opinion survey techniques. In addition, the editorial culture of excellence that he built is still very much in place." In 2024,
Michael Hiltzik wrote in
The Los Angeles Times that "Rasmussen Reports used to be a fairly creditable and credible political polling organization," but that in the years since Scott Rasmussen's departure "Not only have its results become more sharply partisan, favoring Republican and conservative politicians, but it also has increasingly promoted right-wing conspiracy theories." Scott Rasmussen has noted his separation from the firm on social media,
tweeting: "For clarity, I left my old firm more than a decade ago and have had nothing to do with it since." ==Books==
