This map has the familiar pattern of previous mayoral contests. North and west Eugene largely voted for Clark and south Eugene largely voted for Vinis.
The difference is one of degree and of inroads. North and west Eugene were not as supportive and Vinis won several north and west precincts. Compare the 2008 mayoral race: http://lindholmcompanyblog.com/?p=3482.

As with Mike Clark, political party was the top determinant of favorability towards Vinis. As one would also expect, given that Vinis was practically unknown at the beginning of the campaign (see: http://lindholmcompanyblog.com/?p=13040), her name familiarity steadily increased among all groups with her net favorability rocketing among Democrats.

The primary driver of support for Mike Clark was a person’s political party. After that, Democrats split up between those from South Eugene and those from the rest of Eugene. Among South Eugene Democrats, Age was the key factor with persons 60 and under being strongly negative. Among the latter, they got to know Clark better, but didn’t much like what they learned. This group was a key part of the business coalition in past years and the loss of this group explains some of the Clark campaign’s troubles.

In contrast to Mike Clark’s name familiarity trend (http://lindholmcompanyblog.com/?p=13038), Lucy Vinis’ steadily improved. Her favorables and net favorables increased in every poll. By a couple weeks out her favorable-to-unfavorable ratio was a very healthy three-and-a-half-to-one.

Mike Clark’s net favorability (favorables minus unfavorables) never broke into double digits. A typical campaign goal is two-to-one. At one point Clark was nearly one-to-one.
