Political parties are legally formed groups oriented to occupy political power. The power of each party is related to the number of elected candidates it possesses. Just as popularity is associated with the number of voters the party can muster. Power and popularity change over time according to their trajectories. The way parties are aligned with their electoral principles and commitments.
The role of a political party has to do with watching over the rights and interests of the people and the community by presenting candidates to run for public office. The better a political party fulfills its roles in the eyes of the public, the more popular it will be. Also, the popularity of a party is directly linked to its understanding of the people's concerns at any given time. For example, in times of recession and unemployment, the most popular political party will be the one whose members in public office work hard and achieve concrete results to increase employment and solve the economic recession. Conversely, a popular party today may lose popularity tomorrow when it tries to uphold an agenda that people do not share. The same party that gained popularity for increasing employment can lose it for advocating war overseas in times when most people demand peace. Parties often realize they can lose popularity by advancing impopular policies which they usually do because of backdoor negotiations with the government or small groups with agendas of their own.
