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, 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.

Democrat Adelita Grijalva and Republican Daniel Butierez dominated a field of congressional hopefuls Tuesday night to get one step closer to representing a wide swath of southern Arizona in Congress.

Adelita Grijalva on Tuesday won the Democratic nomination for the U.S. House seat her father held until his death in March, emerging from a contested Arizona primary that highlighted broader intraparty divisions over age, experience and dynastic politics.

The next test of who Democratic voters want to see leading the party will take place Tuesday in southwest Arizona, where three leading candidates are offering competing visions in the primary to fill the late Rep.
