Contrary to popular belief, there have only been 3 studies of the impact of lawn signs, and all 3 indicate that lawns signs DO have a positive impact on both turnout and vote share.
In the largest study yet, which just came out this March, lawn signs were responsible for about a 1.7% increase in vote share. A previous study demonstrated that in a low-information local election, they could deliver as much as a 10 point increase in vote share.
This is surprisingly close to the results for canvassing, which are about 1.8% to 2% in vote share and up to 8% in increased turnout.
Lawn signs work in multiple ways:
- providing visual cues for word-of-mouth conversations,
- creating the appearance of viability and momentum,
- increasing name recognition and driving online searches, and
- indicating peer-endorsement by neighbors.
In our program, we aggressively recruit supporters to host lawn signs on their properties, focusing on high traffic routes in geographically targeted areas.
