The election results from San Diego’s northwest council district earlier this month resemble a sandwich. Northern areas like Carmel Valley and southern areas like La Jolla supported Republican challenger Ray Ellis. Central areas like Torrey Pines and University City supported the incumbent councilwoman, Democrat Sherri Lightner.

The map below illustrates the sandwich in District 1 in more detail. Democrat challenger Bryan Pease won the most votes in a couple precincts while Republican challenger Dennis Ridz won none.

Since none of the four candidates got more than half the total vote in the district, the top two, Ellis and Lightner, will advance to a November runoff. The map underscores where they’ll need to work.
