LINCOLN, Neb. (AP) — Nebraska’s secretary of state says this year’s spike in voter registration will not necessarily mean greater participation in the primary election.

In a Monday news release, John Gale encouraged citizens to vote in the May 10 primary to boost Nebraska’s historically low turnout.

This year, 1,165,189 Nebraska voters are registered for the primary, about 13,000 more than were registered to vote in the 2014 primary.

But Gale says Nebraska has not seen more than 300,000 voters participating in each of the past three presidential election years, and registration rarely translates to voting-day turnout.

Gale says counties have reported they have only received about half of the early voting ballots back.

In-person early voting continues until May 9, the day before the primary.
