Navajos hoping to become the next tribal president have until the close of business Wednesday to submit applications.
Nearly a dozen people so far have filed paperwork and paid the $1,500 fee to enter the race.
The applicants include the current tribal president, a former chief justice, a former vice president, political newcomers and others who have held elected office on the Navajo Nation.
Election officials will spend the next two weeks vetting the applications. Candidates also can challenge each other's qualifications.
The top two vote-getters in the August primary will choose their running mates and face off in the Nov. 6 general election.
