Walter Olson at Cato on the Grimmer/Hersh paper. Here’s a key point made by Olson, which I tend to agree with: “[M]any old ideas about who votes for which party are no longer useful. ‘Voter suppression’ narratives often rest on the notion that poorer and less educated voters will be differentially discouraged by some requirement. Nowadays, however—if not 40 years ago—those groups overall may lean Republican.”
