I was the 39th voter at Madison's 41st ward at 12:15 p.m. today. That indicates to me that turnout will be slightly higher this time around than the last time there was a big-ticket primary, in 2007. That year, 92 votes were cast in the mayoral primary. Since most people tend to vote later in the day, especially after they get out of work or classes, I'm guessing turnout will get up to around 110 at the location.
Granted, the primary for county executive is much more interesting and competitive than the mayoral primary from 4 years ago. With such a large field of candidates, it's hard to predict who will make it through the first round. From what I'm hearing, it is most likely to be Parisi and Bruskewitz, but McDonell and Wineke's hopes are not based entirely in fantasy.
The protests are a great opportunity for the campaigns to direct workers to the polls. I hear from Jason Joyce that McDonell and Wineke were on scene at the Square, and I saw a lady passing out flyers for Soglin.
