WATERLOO - Jeff Danielson of Waterloo, the Democratic incumbent in the Senate 10 race, overtook Walt Rogers in the ballot counting Thursday, according to the Black Hawk County Auditor's Office.

Challenger Rogers, a Republican from Cedar Falls, was ahead by 65 votes before provisional ballots were counted Thursday.

The Black Hawk County Special Precinct Board for the Nov. 4 general election met Thursday to count the provisional ballots - from voters who turned in absentee ballots at the polls. The board also counted absentee ballots received late or in dispute.

According to County Auditor Grant Veeder, the board was unable to completly finish its task and will return today. But with the votes that were tabulated Thursday, the following changes took place in the Senate 10 race, as well as the House District 21 race between Republican incumbent Tami Wiencek and Democratic challenger Kerry Burt:

- Senate 10: Election night leader Rogers increased to 16,051 votes, but Danielson increased to 16,057, giving Danielson a six-vote lead.

- House 21: Leader Kerry Burt increased to 6,662 votes, while Wiencek increased to 6,445 votes, so that Burt's lead is now 217 votes.

In other action, Veeder said he will request an administrative recount in two precincts involved in the Senate Distirct 10 race between incumbent Danielson and Rogers.

Reports from precinct officials about problems with a small number of ballots in each precinct prompted Veeder to request the recount Thursday, given the closeness of the race.

Iowa law states the county auditor may request the Board of Supervisors to order an administrative recount if machine malfunctions are suspeced or "if the precinct election officials report counting errors."

Officials at the polling place at University Book and Supply on 23rd Street in Cedar Falls returned 19 unvoted ballots to the Election Office because the voting machine would not accept them. Precinct officials at Our Savior's Lutheran Church in Waterloo said that a ballot that was jammed may have been counted more than once when a voting machine technician came to fix the machine.

Veeder said he will ask the supervisors at the election canvass Monday to set a Nov. 12 date for the Special Precinct Board to meet again for the recount.
