The use of political bumper stickers in Israel began as a spontaneous protest medium, evolving into a routinized form of public discourse, taking place throughout the year, independently of national elections. The rules of interaction of this nontraditional means of political communication are identified and the complex relationships between the messages within their social situation are investigated using an ethnographic model. This analysis reveals that the medium does indeed constitute a structured means of expression with identifiable forms, rules, and usages, affording the person in the street a way of participating in the national discourse, bypassing traditional avenues of influence. The detailed examination of a single political bumper sticker reveals a structure parallel to the overall code, further demonstrating the intricacy of the messages. The analysis shows how this political discourse reflects social norms peculiar to Israel and how its use has become an affirmation of cultural identity. Because the fundamental properties of political bumper stickers have now been exposed, it is possible to examine how the actual use of this medium changes the structure of political agency in society through the presumption that ordinary individuals have the right of access to the public debate of national political issues, a right heretofore exclusively the prerogative of institutional power holders.Over the past few years in Israel, bumper stickers have become part of the local cultural code of political communication. They are routinely discussed in daily interactions, they form the basis for jokes and humor, and they are used in advertisements. Political bumper stickers are used quite differently from election advertising such as buttons, T-shirts, posters, billboards, and the like. This medium is used throughout the year, in response to current political events in the country, regardless of whether or not national elections are currently being held.
