The Arizona Republic reports that the biggest increase in independents occurred between June 2010 and July 2011, and the numbers have basically stayed flat over the past year.
During the two-year period, the number of registered Republicans jumped about 14,000.
But in just the past year, the number of registered Democrats dropped by more than 52,000.
Of Arizona’s 3.1 million registered voters, about 36 percent are Republican, about 30 percent are Democrats and about 33 percent are independents.
Arizona Democratic Party spokesman Frank Camacho says voters are getting tired of the tone of today’s politics.
Tim Sifert, Arizona Republican Party spokesman, attributes the jump in independents to uncertainty about issues.
