It was supposed to be the study that proved voter ID laws are not just discriminatory but can also have a big impact on elections. And it was picked up widely, with outlets including ThinkProgress and the Washington Post reporting that the study found voter ID laws hurt Hispanic voters in particular and skewed elections to the right.
But a follow-up study suggests the findings in the original were bunk. According to researchers at Stanford, Yale, and the University of Pennsylvania, the original study was based on surveys of voters that are extremely unreliable — skewing the results. On top of that, several calculation errors led to even more problems. When the errors are corrected, the follow-up researchers found, there’s no evidence in the analyzed data that voter ID laws have a statistically significant impact on voter turnout.
