Arizona's voter registration numbers have dropped by about 3,000 since the last report in July.
The Secretary of State's Office announced Wednesday that Arizona still 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 more than 1.1 million Republicans, about 965,000 Democrats and more than 1 million independents.
Members of the Libertarian, Green and Americans Elect parties account for about 1 percent of the electorate.
