Navajo voters have a record number of candidates to choose from in Tuesday's presidential primary election.
The race drew 18 candidates. The top two vote-getters move on to the November general election.
The candidates have touted plans for economic development and securing water rights, providing services to veterans and the elderly, and bringing younger Navajos back home.
The reservation is the largest in the country, extending into New Mexico, Arizona and Utah.
More than 93,000 Navajos are registered to vote in the election.
