Arizona Democrats have removed their chair just six months into a tumultuous tenure. Two-thirds of the state Democratic committee voted Wednesday to oust Robert Branscomb following public disputes with top Democratic leaders and concerns about fundraising.

For the second time in less than a year, Arizona business owner Dan Butierez will be facing a member of the Grijalva family in a U.S. congressional election.

The election to replace the late Rep. Raúl Grijalva is ultimately expected to send a Democrat to Capitol Hill, putting pressure on House GOP leaders.

While Tuesday's special election in Arizona may not seem like the type of story to generate nationwide headlines, the race is getting eyes across the country for boiling down the current state of the Democratic Party into a single election.

Republican nominees competed in Arizona's special primary election for the 7th congressional district seat previously held by the late Democrat Rep. Raúl Grijalva.

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.

Grijalva's daughter is the presumptive frontrunner in the 7th Congressional District's July 15 Democratic primary.
