A Chicago area joke suggests there are two seasons: winter and construction. I would like to propose a third and occasional season: political yard sign season.

This season is a regular occurrence even as it does not show up every year, it might be more visible on the 4 year presidential election cycle, and it occasionally occurs during primary voting periods in the spring. On its more regular schedule, by early October numerous lawns and public intersections contain political yard signs. Lawns – usually clear of obstructions – broadcast political messages for those passing by. They range from national offices (president, Senate, House) to very local offices (townships, local forest preserves, etc.). They differ in size – some huge, some small and hard to read – and in color, often tied to the traditional colors of the two major parties with some occasional other colors thrown in.

Most lawns do not have signs. Some property owners have them each political yard sign season, others are more occasional participants. The corners of major intersections can be little battlegrounds as people place signs for different candidates and different races.

What difference does political yard sign season make? I do not know. Do those going by at suburban driving speeds (1) have time to read the signs and (2) ever change their preferences or voting patterns? Is it more about political mobilization among residents where signs are symbols of their fervor? For the stories and images I see of signs stolen or removed, do these actions change anything?

Soon political yard sign season will pass. Election Day comes and the signs disappear rapidly. Some might hang on for a while longer, braving the cold and snow of winter. Almost none will be around for the coming of the next construction season. For a short period, political yard sign season blooms and we all experience it.
