PHOENIX -- Arizona's voter registration numbers have risen by about 2,300 since the last report in April.
The Secretary of State's Office announced Tuesday that Arizona has more than 3.2 million registered voters.
While the state's major political parties experienced a decrease, the number of voters not affiliated with any party increased slightly.
Nearly all of the electorate is divided roughly into thirds, with 1.1 million Republicans, about 973,000 Democrats and more than 1 million independents.
Members of the Libertarian, Green and Americans Elect parties account for about 1 percent of the electorate.
