State Sen. Michele Reagan has announced her long-expected candidacy for the Republican nomination for secretary of state.

The secretary of state in Arizona is the state's top election officer and also becomes governor if there's a midterm vacancy in that office. Arizona does not have a lieutenant governor.

Incumbent Ken Bennett is barred by term limits from running for re-election.

Rep. Justin Pierce and investor Wil Cardon also are running for the Republican nomination.

Reagan announced her candidacy Tuesday evening.
