Hernandez, 40, of Maryvale, made a name for herself in the Valley as an advocate for causes that support the legalization of undocumented immigrants.
She also has drawn criticism from some Democratic leaders at the state Legislature, who worry about misdemeanor traffic convictions, an arrest for suspicion of human trafficking and questions about her husbands' legal status.
She says her life experiences will make her an effective lawmaker; others disagree.
"The citizens of Arizona are very concerned about this situation," said Rep. Robert Meza, D-Phoenix. "We want to get the most competent, ethical person in District 13 - someone who is solution-driven as opposed to a bomb-thrower."
Meza said he was most concerned about a 1999 incident in which Hernandez was detained and questioned on suspicion of transporting undocumented immigrants southeast of Tucson. Hernandez was cited for speeding but was never charged with transporting immigrants. Records in the case were purged and sealed in 2007.
District 13 candidate's legal woes worry some lawmakers
They should be concerned. The treasonous handwriting is on the wall . . . .
