“Mr. Richman relies on a one-of-a-kind poll: the Cooperative Congressional Election Survey. Every two years, a consortium of 28 universities produces a detailed report on voters and their views based on polling by YouGov.
Tucked inside the lengthy questionnaire is a question on citizenship status: A significant number of respondents anonymously acknowledged they were not citizens when they voted.
Three professors at Old Dominion University — Mr. Richman, Gulshan A. Chattha and David C. Earnest — took these answers, did further research and extrapolated that of a 19.4 million estimate of adult noncitizens, about 620,000 were illegally registered to vote in the 2008 presidential election. Using other measuring tools, they said, the actual number of noncitizen voters could be as low as 38,000 and as high as 2.8 million.”
It’s time to clean up voter registration rolls.
