Distribution of Mayoral Vote Pcts. by Precinct

image004

This graphic ranks Lucy Vinis’ net percentage over Mike Clark in the 2016 Mayoral Primary for each of Eugene’s 31 precincts. It is a good way of presenting the geographic concentration of voting.

Several things stand out. First, this confirms the result in the last post. Vinis, like Piercy, won by winning big in a relatively small part of the town. Vinis won a number of precincts by nearly 60% while Clark only won one by more than 30%. Second, rather than a nearly continuous line there is clustering and a break. Ten precincts gave Vinis a margin of 50% or better. On the other hand, less than half a dozen precincts gave her a win by between 0% and 30%. Finally, there is little clustering in the Clark precincts. They form a nice continuous line.

It is worth noting that this overstates the margin of Vinis’ win. The precincts Clark won tend to be larger.

Source of data: Lane County Elections

Methodology: The margin equals the Vinis percentage minus the Clark percentage.
