Voter Preference or Visual Pollution?

With the campaign season at its height, election propaganda has saturated our lives. Yard signs, buttons and live debates all try to persuade us to cast our votes in a particular direction. Political society scrutinizes everything from size and placement of signs to the potential backlash and spin of negative advertising. Taking a casual glace at our landscape, some could debate whether campaign advertising has reached a point of diminishing returns. Does a discarded sticker really aid political understanding or simply litter the sidewalk? Does a flurry of campaign signs actually encourage voting or simply mar the ambience of downtown? Are we visually shouting so loud that we have become numb to the process?
