Politicians take benefit from showing their image to the public, including positive biases created by the media, for example, photographies. They use scenarios which have been prepared in full detail, to take pictures that will be considered attractive by their voters, or that can gather more supporters.
For example, see in the photo attached how Hilary Clinton publishes during her presidential campaign a photo where she appears smiling together with a black woman. Such a picture in which she appears in a quite comfortable mood with the other woman, creates the general idea of how supportive she is with minorities or discrimined ones, in this example, two collectives together: black people and women.
