What is a Precinct Committeeman, and why would I care?

A Republican Precinct Committeeman (PC) represents the GOP voters of his or her precinct at the County Republican Party level. But most importantly, a Republican Precinct Committeeman is the face of the GOP within the precinct. Arizona law defines a party's neighborhood leaders as Precinct Committeemen, who are elected by voters and have a duty to help their fellow Republicans vote. The state of Arizona is divided into 30 Legislative Districts. The Legislative District (LD) is the basic political operating unit.
