A politician's concern is typically focused on gaining and maintaining power. This is often done through IMAGE, primary elections, and spheres of influence. IMAGE is the public perception of a politician, which can be cultivated through media appearances and other public relations efforts. Primary elections are the first round of voting in an election, where voters choose which candidate will represent their party in the general election. Finally, a sphere of influence is the area of power and influence a politician has over their constituents.
