In a celebratory display of unprecedented organization, a bipartisan group of activists poured into the Arizona secretary of state's office yesterday with more than 18,300 signatures to demand the recall of State Senate president Russell Pearce. The filing of the petitions marked the culmination of a campaign that has defied expectations, and a watershed moment for the beleaguered state. Once the state and Maricopa County recorders verify the legal requirement of 7,756 signatures from the traditionally conservative and Mormon-founded Mesa district, Pearce—who is considered by many as the de facto governor and motivating force behind the state's notorious blitz of extremist policies on education, health, guns and immigration—will become the first State Senate president in American history to be recalled.
