One effective strategy used by political campaigns is to communicate information to the public about the candidate or issue.
Candidates are expected to bring solutions to a certain comunity problems so, when they postulate, they have to declare what their propositions to solve the comunity issues are, as well as their plans to take them to reality. In addition, all information provided on the candidate exalts his or her qualities in order to persuade voters to pick them, regarding they are different from the ones that preceded them and, thus, will make an actual change in the comunity.
