 At a Wisconsin rally, presidential candidate Donald Trump claimed that non-US citizens have voted in, and significantly affected the outcomes of, previous elections. However, IQSS affiliates [Stephen Ansolabehere](/people/stephen-ansolabehere), [Brian Schaffner](/people/brian-schaffner), and YouGov managing director [Samantha Luks](https://today.yougov.com/people/samluks/), explain how this claim cites a questionable study. In their recent article for the *Washington Post*, Ansolabehere, Luks, and Schaffner explain, "We argue that the findings in the Richman et al. article can be entirely explained by measurement error. Specifically, survey respondents occasionally select the incorrect response to a question merely by accident." The full article, including references and links to the cited study and subsequent rebuttals, can be found [at the Washington Post](https://www.washingtonpost.com/news/monkey-cage/wp/2016/10/19/trump-thinks-non-citizens-are-deciding-elections-we-debunked-the-research-hes-citing/#comments).

 The Cooperative Congressional Election Study is an annual multi-institutional study, headed by Stephen Ansolabehere (Harvard Dept of Government) and Brian Schaffner (UMass Amherst), which involves a two-part national survey administered by a team at YouGov/Polimetrix led by Samantha Luks. More information about the Cooperative Congressional Election Study is available at the [CCES website](http://projects.iq.harvard.edu/cces/%E2%80%9D).
