"A lot of it was SB 1070 [anti-illegal immigration act] and what [Maricopa County Sheriff Joe Arpaio] was doing in our communities that really triggered it," Guevara tells Raz. "Also, tuition increases and a lot of our Dream Act students basically got kicked out of school because of a proposition that increased tuition significantly."
Critics say Arizona's new immigration law encourages profiling. Republican Sheriff Arpaio's office was
cited by the Justice Department for "pervasive culture of discriminatory bias against Latinos." And the Dream Act, which proposes paths to citizenship for some undocumented children of immigrants, is largely opposed by Republican lawmakers.
The issues Guevara mentions among others mobilized so many people in western Phoenix that it eventually inspired a recent
Time Magazine cover story.
"In the end, we witnessed the greatest grassroots effort in the history of Phoenix politics," Valenzuela says.
The success prompted the Obama campaign to send an operative to Phoenix to learn more about Valenzeula's game plan and how to apply it nationwide; Valenzuela says he believes Arizona is in play this election.
"The Latino voter turnout increased by nearly 500 percent in one particular district," he says, "but over the city of Phoenix, which is the sixth-largest city in the country mind you, it actually increased by over 300 percent across the board."
Latinos like the ones who voted in Phoenix people who had never voted before could turn out across the country in such numbers this year that they might hold the power to swing the presidential election.
The way things are looking now, that's bad news for Republicans.
"When I hear some of the policies and the rhetoric that's coming out of the GOP debates, I hear very little other than anti-immigration reform," Valenzuela says. "And those things bother me, personally, and I know that I'm not alone."
