Lincoln residents might need a scorecard to keep track of the candidates in the upcoming June election.

Up for grabs are the position of mayor and three council seats. Judge Charles Isakson is running unchallenged for municipal judge and voters will be asked whether minutes are to be published in the official newspaper.

Incumbent Glenn Christmann is being challenged by former commissioner and former acting mayor Mary Ann Filibeck for mayor. Running for council are incumbents Robert Johnston and Peter Horner while Marie Horning, Reid Unterseher and Steven Urlacher are challenging.

Christmann is recovering from recent heart surgery but is expected to be ready for the election. He was elected to the council in 2000 and defeated incumbent Johnston for mayor in 2004.

Johnston was first appointed to the council in 1998, then won a recall election for mayor in September of 1998 and was re-elected mayor in 2000. He was defeated in 2004 by Christmann and then won a council position in 2005 during a recall of city council members. He is now seeking re-election to the council.

Filibeck holds the distinction of having served the community as both a council member and acting mayor. She was first elected in 1996 as a council member and became acting mayor in 1998 during a tumultuous time in the history of Lincoln's council. She has twice been recalled, losing her spot on the council in 1998. Filibeck was appointed to the council in April of 2005 and survived a recall in September of the same year, though she decided against running for re-election in 2006.

Urlacher was appointed to serve on the council in place of Andrew Horning, who is serving in Iraq on a National Guard assignment. Urlacher is now running for his own seat on the council. Should he be successful, the council will have to find another replacement for Horning until he returns.

Marie Horning, Andrew's wife, is running for a council seat. She has served the council in many capacities over the past few years as a member of planning and zoning.

Council member Horner is seeking re-election. He served on the council in the early 1980s and was elected to the council in 2004 after many years of absence.

Unterseher is running for the council and is a member of the National Guard's 112th Command Aviation Battalion.

The council is in the process of reducing its members from seven to five, a move overwhelmingly endorsed by Lincoln voters in the 2006 election.

Two of the three council positions are for four-year terms and the remaining seat is for two years. The top two vote getters for the council in the election will get the four- year terms with third place getting a two-year term.
