Washington State 2016 Presidential Race – Overview

As explained on our home page, an election should normally obey the law of large numbers fairly well, unless there is a strong reason for people in larger precincts to vote one way rather than another.

In terms of demographics, it has long been noted that very small districts are more likely to be found in rural areas, which tend to be more conservative, so often the red line is higher and the blue line is lower toward the very left. Typically though, the line goes horizontal rather quickly.

In Washington State we see this pattern almost without fail, the exception being Kittitas County, above.

With the notable exception of Kittitas County, each county in the state appears to obey the Law of Large numbers fairly well, although there is typically a slight “blue shift” that is probably due to a more liberal city with larger precincts surrounded by small rural conservative precincts. Even in these cases our cumulative vote total lines become relatively horizontal toward the right side of each graph. Spokane County and Chelan County are examples.
