Campaign buttons are small, often round pins that display a political message, candidate's name, or slogan. They are commonly used during election campaigns to promote candidates and engage voters. These buttons can be worn on clothing, bags, or hats, making them a popular form of grassroots marketing. Historically, campaign buttons date back to the American presidential election of 1896. They have evolved from simple designs to more elaborate graphics, reflecting the personality and values of the candidate. Today, they remain a staple in political campaigns, serving as a way for supporters to show their allegiance and spark conversations about the issues at hand.
