JLF head John Hood’s column yesterday is on the impact of the U.S. Supreme Court allowing November’s election to proceed under new rules passed by the Republican-controlled General Assembly last year. John’s key point:

Although the 2013 law’s photo ID requirement won’t be in effect until 2016, Democrats fear that other changes going into effect this cycle — such as confining early voting to 10 days rather than 17 and requiring Election-Day voters to cast ballots in their assigned precincts rather than casting provisional ballots elsewhere — will depress turnout among Democratic-leaning constituencies. It is also possible that some Republicans hope these changes will reduce turnout among Democrats. Many certainly believe that the changes will deter fraudulent voting. If voter fraud is widespread, then deterring it would clearly result in lower measured turnout.

Based on the best-available empirical evidence, however, neither side is correct. With one exception, none of the changes to North Carolina election laws will likely affect voter turnout to any perceptible degree.
