PHOENIX (AP) — Adelita Grijalva won the Democratic primary Tuesday for a southern Arizona U.S. House seat long held by her father, the late U.S. Rep. Raúl Grijalva, one of the most senior and progressive power brokers on Capitol Hill.

Southern Arizona Democrats have crowned Adelita Grijalva the victor of a July 15 U.S. House special primary election, setting the former Pima County supervisor on a glide path to succeed her father in Congress.

Adelita Grijalva, the daughter of the late Rep. Raúl Grijalva, won the Democratic primary in the special election for Arizona's 7th District.

Adelita Grijalva beat Democratic influencer Deja Foxx to win the special primary for Arizona’s blue 7th Congressional District to fill out Raul Grijalva's term.

The race between Grijalva, who was running to succeed her father, and content creator Deja Foxx highlighted broader intraparty divisions over age, experience and dynastic politics.

Arizona's Rep. Raul Grijalva died in March at 77. His daughter, Adelita, is one step closer to taking up his mantle in Washington.

Adelita Grijalva, daughter of the late Congressman Raúl Grijalva, won Tuesday's Democratic primary in the special election to replace her father, and will advance to this fall’s general election.
