In recent years, the term political moderates has gained traction as a buzzword. The existence of the ideal moderate is disputed because of a lack of a moderate political ideology. Voters who describe themselves as centrist often mean that they are moderate in their political views, advocating neither extreme left-wing politics nor right-wing politics. Gallup polling has shown American voters identifying themselves as moderate between 35–38% of the time over the last 20 years. Voters may identify with moderation for a number of reasons: pragmatic, ideological or otherwise. It has even been suggested that individuals vote for ‘centrist’ parties for purely statistical reasons.
