Early voting has not led to more voting in Ohio, at least not in terms of total votes cast.

A Dispatch analysis of the vote totals from the past three presidential elections in the state shows that overall turnout in the 2012 race, when Ohioans arguably had the most opportunities in state history to vote early, was lower than in the 2004 election, when there was virtually no early voting in Ohio.

Seems to me that a study which accounts for the affect of early voting on turnout needs to do more than just look at total votes cast.
