Some Kansans who say they recently registered to vote when they got their driver's license are finding that their registration wasn't recorded.

The extent of the problem is not known. Kansas Secretary of State Ron Thornburgh said he was aware of approximately 90 cases concentrated in Johnson, Shawnee and Butler counties during advance voting.

Sedgwick County Election Commissioner Bill Gale says his office has been seeing an average of 100 advance voters who registered at a DMV location daily. Only a handful, however, have had problems.

In all instances, the people were given provisional ballots, and whether their votes will be counted will be determined after the election, officials said.

Thornburgh said the voter registrations are not showing up because of either errors by the clerks at the DMV or the person is simply mistaken that they applied to register to vote. He said he didn't think it was an error in the computer software.
