Raúl Grijalva announced he’s running for a seventh term in Congress at a kickoff party in Tucson Sunday night. 

Grijalva, a Democrat, said he’s often asked whether he’s tired of dealing with the Republican majority and the Tea Party in the House. “The answer is yes,” he said in a speech to supporters.

But, he said, he’s energized by his constituents and he wants to keep working on problems including income inequality, immigration reform and environmental issues. Education reform is still on his agenda, “and I’m not tired of fighting for it,” he said.

Grijalva represents District 3, which includes parts of Pima, Maricopa, Pinal, Santa Cruz and Yuma counties.

The most recent voter registration numbers show 42 percent of voters in the district are Democrats, 37 percent are independent, and 21 percent are Republicans. 

Grijalva’s 2012 challenger, Gabriela Saucedo Mercer, is running again, too. 

At a speech to the Pima County Republican Club last month Saucedo Mercer said she was proud she received almost 40 percent of the votes in her first-ever campaign even though Grijalva outspent her 4 to 1.

She said she will run a more grassroots campaign that focuses more on Maricopa County, where nearly a third of District 3 voters live.

Grijalva had $109,158 in his campaign coffers at the end of the calendar year. Mercer had just $773 in cash on hand. 

Race newcomer Miguel Olivas is running against Saucedo Mercer in the Republican primary. He plans to make an official announcement in May.
