Recent Eugene Area Net Partisan Swing Margins


This chart goes over the swing margins in some recent contests. The idea is that not every district is created equal. In particular, it’s pretty easy for a Democrat to build up a big margin in Eugene. Similarly, it’s relatively easier for a Republican to win in rural Lane County than in Eugene.

Farr’s margins, despite facing an incumbent in 2012 and an opponent with a long resume in 2016, were the largest of the group.

The standard swing in the state legislature or in other areas of the state is under 10%.
