Moderate
From dKosopedia
A moderate is someone who balances their position with the position of those around them, thereby reaching if not a center point, a kind of stable equilibrium which is able to balance opposing viewpoints. A moderate typically avoids partisan positions or does not consistently side with any one political party or ideology in taking positions. Some "moderates" are politically apathetic and use "moderation" as a way to average the advice of experts as presented to them in the various media. Such voters often place more emphasis on the personality of a candidate than his or her issue positions. When legislative bodies are fairly evenly balanced, as is the case now in the U.S. Congress, moderates hold the power to decide most partisan issues.
