Irma Maldonado, 18, plans to use her vote to “say no to Donald Trump,” but she’s not sure she’ll vote for Clinton. “I think it would be awesome if we had the first woman president,” she said.

“Latinos are largely young, still too many Latinos don’t graduate from high school, much less college, and as a result Latinos disproportionately live in poverty, so what you are talking about are three very tough groups to get out to vote,” says Joseph Garcia, director of the Morrison Institute’s Latino Public Policy Center at ASU.

Ian Danley, director of One Arizona, says that in Maricopa County, efforts have focused heavily on the disproportionately high number of Latinos who are eligible to vote but aren't registered.
