Political signs are a staple of election seasons, popping up in yards, along busy roads, and in front of businesses. But do these signs actually influence election outcomes, or are they just a tradition? While political signs alone won’t guarantee a win, research suggests they do play a role—especially in local and down-ballot races where name recognition matters most.
The Power of Name Recognition
One of the biggest advantages of political signs is their ability to increase name recognition. For local elections, where candidates may not have a large media presence, getting their name in front of voters is crucial. Studies have shown that repeated exposure to a candidate’s name through signage can create familiarity, which can translate into votes.
A study referenced by NPR even found that fake candidates, introduced only through signage, gained recognition and support simply because people saw their names frequently. This highlights how yard signs, banners, and posters can help unknown candidates gain traction.
Do Political Signs Increase Vote Share?
Yes—but to a limited extent. Research published in Electoral Studies examined four field experiments and found that political yard signs can increase a candidate’s vote share by just over 1 percentage point. While this might seem small, in tight elections, a single percentage point can be the difference between winning and losing.
Signs are particularly effective in local and state elections, where voters may not have as much exposure to candidates through television ads or debates. In national races, the effect of signs is much smaller compared to larger campaign strategies like digital ads, direct mail, and television appearances.
Signs as a Voter Mobilization Tool
Political signs do more than just promote candidates—they can help increase voter turnout. When people see a high volume of signs for a particular candidate, it can create a “bandwagon effect,” where undecided voters may be influenced by the apparent popularity of a candidate. Additionally, signs serve as constant reminders of an upcoming election, encouraging people to vote.
For campaigns, strategically placing signs in high-traffic areas can help reinforce a candidate’s presence and encourage voters to take action.
The Verdict: Do Political Signs Matter?
While political signs won’t single-handedly win an election, they are a valuable tool in a campaign’s strategy. They help increase name recognition, provide a visual presence in communities, and remind people to vote. In local and close elections, a well-placed sign could make a small but meaningful difference.
For candidates, the best approach is to use signs as part of a larger strategy—combining them with digital ads, direct voter outreach, and strong policy messaging to create a comprehensive campaign.
