More rightardedness. <smh>
When they say their findings are "based on survey data from the Cooperative Congressional Election Study," what they don't say is that survey was an unscientific non-probability online poll...
Methodological challenges affect study of non-citizens’ voting
A number of academics and commentators have already expressed skepticism about the paper’s assumptions and conclusions, though. In a series of tweets, New York Times columnist Nate Cohn focused his criticism on Richman et al’s use of Cooperative Congressional Election Study data to make inferences about the non-citizen voting population. That critique has some merit, too. The 2008 and 2010 CCES surveyed large opt-in Internet samples constructed by the polling firm YouGov to be nationally representative of the adult citizen population.
Furthermore, it was determined that respondents were wrong at best, or lied at worst, when claiming their immigration status...
It turns out that such response error was common for self-reported non-citizens in the 2010-2012 CCES Panel Study — a survey that re-interviewed 19,533 respondents in 2012 who had currently participated in the 2010 CCES. The first table below, for instance, shows that nearly one-fifth of CCES panelists who said that they were not American citizens in 2012 actually reported being American citizens when they were originally surveyed for the 2010 CCES. Since it’s illogical for non-citizens in 2012 to have been American citizens back in 2010, it appears that a substantial number of self-reported non-citizens inaccurately reported their (non)citizenship status in the CCES surveys.
