What is Triangulation?

Legal Definition
In politics, triangulation is the strategy in which a political candidate presents their ideology as being above or between the left and right sides (or "wings") of a traditional (e.g. American or British) democratic political spectrum. It involves adopting for oneself some of the ideas of one's political opponent. The logic behind it is that it both takes credit for the opponent's ideas, and insulates the triangulator from attacks on that particular issue.
