Thirty-one thousand Illinois voters turned in online applications.
That's according to the State Board of Elections, which says more than a third of those arrived in the final two days before last week's deadline.
It was the first time Illinois allowed applicants to register online.
Voting rights groups pushed for the change. Critics question the process's ability to properly screen identities.
Midterm elections typically see lower turnout, and the negative tone of the governor's race could result in voter apathy. But the online registration is one of several changes this election year that could drive up turnout in Illinois.
