A pair of Spirit Lake candidates have met the filing deadline to potentially fill the open Iowa Senate District 1 seat vacated by former State Sen. Zach Whiting late last month. Candidates Mark Lemke and Dave Rowley will both appear on the Dec. 14 special election ballot. Rowley was selected as the Republican nominee during a special district convention on Nov. 11, and Lemke was chosen by the district's Democratic Party on Nov. 17. The special election for the open seat has been set for Dec. 14, and the successful candidate will fulfill the final year of Whiting's term — possibly facing challengers come the next primary and general elections.
