Voter registration in Arizona declined slightly in the first three months of 2013, the Secretary of State's Office reported.

Figures released Friday showed a little more than 3.2 million registered voters, a decline of 2,683 since January.

The breakdown of party affiliations remained roughly the same, with 35.4 percent registered Republican, 30.4 percent registered Democratic and 33.3 percent registered independent or no party. Among other parties, Libertarians were the largest, with less than 1 percent.
