David Crowe Robles, a local defense contractor, is announcing plans this week to take on Congressman Raul Grijalva in the Aug. 28 Democratic primary.

Crowe Robles, who had been toying with a run for U.S. Senate in the Democratic ticket before Richard Carmona got into the race, isn't the only Democrat who wants a piece of Grijalva's hide. Former state lawmaker Amanda Aguirre is also assembling a campaign. Aguirre has Grijalva's old nemesis, Luis Gonzales, helping her make introductions around Tucson.

Grijalva could have trouble in a primary; he nearly lost the overwhelmingly Democratic district in last year's general election because many voters were turned off by his call for a boycott in the wake of SB1070. But his life is probably made a little easier with two opponents instead of just one.

The press release from Crowe Robles after the cut:

Democrat David Crowe Robles looks to put Congressman Raul M. Grijalva out of work and will officially announce his candidacy in the race for U.S. Representative in the new Third Congressional District. Citing the lack of jobs in the district, that for the last 10 years Grijalva has represented, led to this important decision.

“We’ve had enough of politicians who are more interested in keeping their own jobs than in creating jobs for the people they represent,” he said.

Crowe Robles, a Mexican American businessman who grew up in the agricultural areas of Yuma and San Luis Rio Colorado Valleys and now lives in Tucson where he is the President/CEO of Tucson Embedded Systems, a consulting company specializing in aerospace, defense and commercial industries. He notes that the district has some of the most important employers in Arizona, and he intends to bring more industries to the area by supporting small business owners.

A graduate from the University of Arizona with a degree in computer engineering, he is a fourth-generation Arizonan, married and has two children. Now Crowe Robles wants to represent the citizens of this district. “The time has come to send our best person to represent our state and bring jobs to the people of Arizona; I have 17 years experience in creating jobs.”
