Eugene’s politics are famously divided. Below is a map of the precinct results from the 2008 Mayoral Election.
The map colors come from the logo colors for the two campaigns: Piercy is blue and Torrey is green.
For a more detailed look, please see the 2008 Eugene Mayoral Results by Precinct.
By way of comparison, here is an earlier post the precinct-by-precinct returns for San Jose: http://lindholmcompanyblog.com/?p=692. It is not directly comparable because the map is scaled rather than dichotomous and Reed defeated Chavez by a wide margin. However, very few Eugene precincts were not landslide victories, so scaling would have little impact.
