CARSON CITY, Nev. (AP) — Elections officials say Nevada Republicans out-registered Democrats for the second month in a row. Secretary of State Barbara Cegavske says Republicans added 3,870 voters to their rolls in May while Democrats added 2,354 voters.

Democrats still have a lead among Nevada's 1.6 million registered voters. They make up 39% of "active" voters, which are voters who participated in at least one of the last two federal elections. Republicans make up 33% and unaffiliated voters are 23%.

Voters have to affiliate with a political party to cast votes for many of the races in June's primary election.
