From the moment that, in an election campaign, there are posters on telephone poles or balconies showing the facial features of candidates-and we all know how important that is-to have one's picture on telephone poles or balconies, to have the photographs of just a few candidates on a ballot would be detrimental to those whose picture would not appear.
It is better to have a photo of a candidate than not have one during election year.
From the passage above, it tells me that you have a better chance of winning if your photo is there.
