WINDOW ROCK, Ariz. (AP) — The race to become the Navajo Nation's next president features a mix of lawmakers, political newcomers, former tribal officials, a woman and the incumbent.

Navajo President Ben Shelly is seeking a second term in the post. He'll be challenged by 16 others who met this week's deadline to file for the race.

Among them are former President Joe Shirley Jr., and tribal lawmakers Kenneth Maryboy and Russell Begaye. Carrie Lynn Martin is the sole woman in the race.

The primary election is set for Aug. 26. Voters will choose two candidates to move on to November's general election.

Navajos also will be voting to fill 24 seats on the Tribal Council. One lawmaker, Jonathan Nez, is running unopposed.
