The only person challenging him on the ballot was Republican Edna San Miguel, who was in Pima County Superior Court Tuesday for a hearing to challenge her candidacy. She withdrew from the race.
She asked the judge to allow her to run for the seat as a write-in candidate, but state law does not allow someone who has failed to qualify for the ballot for another reason to run as a write-in.
San Miguel's withdrawal clears the race for Grijalva, D-Tucson, unless another candidate seeks the seat as a write-in before mid July.
Other candidates who sought political office this year also will not be on the ballot.
In Pima County Superior Court Friday, Judge Catherine Woods removed Democrat Jeff Farrell from the ballot for the county Board of Supervisors in District 1. That leaves Brian Bickel as the only Democrat in the race. He will face the winner of the Republican primary between incumbent Ally Miller and challenger John Winchester.
In the county constable race for Precinct 1, candidate Stephen St. Clair voluntarily withdrew from the Republican primary Friday, amid a challenge to his qualifications to be on the ballot. That race will be decided in the Republican primary between John Rademaker and Michael R. Smith.
