Hundreds of Wisconsin voters who think they registered in advance will have register at the polls today, state elections officials said.

That's because the group Women's Voices. Women Vote, of Washington, D.C., submitted a large number of voter registrations after the deadline for mail-in registrations, said Kevin Kennedy, director of the state Government Accountability Board, which oversees elections.

Accountability Board spokesman Kyle Richmond said mail-in registrations to the state had to be postmarked by Jan. 30 to be counted.

The group also used the Web site www.voterparticipationcenter.org, Richmond said.

Voters who tried to register through the group will be able to register at their polling place by bringing a proof of address and their driver's license number or, if they do not have a driver's license, their state identification card or final four digits of their Social Security number.
