Politics, in a democracy, exists to allow peaceful co-existence of a multiplicity of voices and peoples. Yes, different visions of the good are brought into competition with each other in politics, and because of this, politics has a competitive character. Yet, if the competitive character of politics becomes its end, politics is deformed. Put another way: winning, narrowly conceived as one vision decisively winning over another, is not end of politics–politics actually exists to prevent such winning–otherwise, given human nature, multiple voices and peoples cannot exist peacefully side by side.
Thus, one could say that the end of politics is love, not competition. It allows people of all kinds of difference to exist with each other, rather than defeat each other.
