Results have been posted by the city, here.Chris Riley had 113 votes, 53%. Ida Theis had 45 votes, 21%. That makes them the top two candidates. If I added correctly, only 212 votes were cast.
The city website, elections page, notes,
"Following the Special Primary Election, a Special General Election will be held on Tuesday, April 10, 2018. The two candidates who receive the most votes at the Special Primary Election will be on the ballot for the Special General Election."
All for now. When the date that early voting opens for the runoff between Riley and Theis is posted on the city site, this post will be updated with that info.
UPDATE: In-person absentee voting begins on Friday, February 23.
