As a field staffer, I know that supporters are constantly asking for yard signs. This tweet is an example of a supporter who is interested in a yard sign. A few dollars to keep a supporter engaged and continuing to contribute time and money is worth it. I have had supporters scream and curse, slam doors and threaten to vote for the opponent over yard signs. Depending upon the campaign’s strategy, it’s difficult to justify a large yard signs when the campaign coffers are limited but getting yard signs for supporters who are passionate about them is a good investment.
