A politician is a person who participates in policy-making processes, usually holding a position in government. Politicians represent the people, make decisions, and influence the formulation of public policy. The roles or duties that politicians must perform vary depending on the level of government they serve, whether local, national, or international. The ideological orientation that politicians adopt often stems from their previous experience, education, beliefs, the political parties they belong to, or public opinion. Politicians sometimes face many challenges and mistakes that may affect their credibility and ability to persuade. These mistakes include corruption resulting from their misuse and exploitation of power to achieve their interests, which requires them to prioritize the public interest and develop long-term strategies. Challenges include how to keep up with the development of social media and confronting biased media, in addition to discrimination against them on the basis of gender, race, or belief, which requires them to adapt their communications to engage citizens, confront discrimination, and spread their message effectively.
