05/12/21 Former Lone Tree Mayor Jon Green emerged as the Democratic candidate chosen to run for the open seat on the Johnson County Board of Supervisors. It took three rounds of voting for Green to secure the nomination Tuesday night as Johnson County Democratic delegates met at the Fairgrounds. Convention rules require a candidate to receive a majority vote to win. He received 105 of the 281 votes in the first round, with Susan Vileta being eliminated. In the second round, Green got 116 of 281 votes, with Scott Finlayson eliminated. In the closely-contested third round, Green edged the remaining candidate, Coralville city councilor Meghan Foster, 139-137.
