Topeka ? Kris Kobach held a tiny lead with the final, unofficial results tallied Tuesday night in the 3rd Congressional District Republican primary, but the numbers could change, and rival Adam Taff wasn’t conceding.

Kobach’s margin was only 87 votes out of more than 86,000 cast. He had 38,124 to Taff’s 38,037, giving both candidates 44 percent. State Rep. Patricia Lightner captured the remaining 12 percent, or 9,944 votes.

Taff, the GOP nominee in 2002, did not stop campaigning after losing a close general election race to Democratic Rep. Dennis Moore that year. Kobach is a former U.S. Justice Department official.

In a speech at an election-night gathering, Taff told supporters: “Stay with us for the next several days.”

“I believe there some things to the order of 300 bags of uncounted votes at the Johnson County election office, so folks it’s going to be a while,” he said.

Taff didn’t give more details, but he may have been referring to provisional ballots, which voters cast but election officials set aside because there are questions about them.

Jesse Borjon, a spokesman for the Kansas Secretary of State’s office, said it did not know how many provisional ballots there were in the 3rd District race. Local boards of canvassers — typically county commissions — have until Monday to review provisional ballots and decide which ones will count, he said.

In early returns, Taff had a sizable lead, but it melted away, and votes from Douglas County, put Kobach ahead.

The only other Kansas congressional primary was in the 4th District, where Michael Kinard defeated Marty Mork for the Democratic nomination, setting up a match with Republican Rep. Todd Tiahrt. With most precincts reporting, Kinard had 73 percent of the vote.
