Lynch and Chelsie L.M. Bright examine the introduction of Kansas’ recent voter ID law. They find that in one county, the distribution of materials reassuring voters about provisional ballot procedures and efforts to make voter ID easier to obtain, meant an increase in turnout compared to other precincts.
