The LIBRE Initiative, an expanding grass-roots organization now operating in nine states, organized the four-hour test prep session to teach the rules of the road in Spanish — no tome y maneje (no drinking and driving), el límite de velocidad es sesenta y cinco millas por hora (the speed limit is 65 miles per hour).

Paula Hernandez, 46, an undocumented restaurant supervisor from Mexico, was one of those sitting on folded chairs, listening. She has worked in the United States for 25 years and gave birth to three children here. She has never heard of the Koch brothers or LIBRE but said the free classes were a “great help,” particularly because nobody else is lending her a hand. “President Obama promised to do more for us, and it just didn’t happen,” she said…

By providing tax prep and driving classes, they are building goodwill in the Latino community and what they call a “platform for civic engagement.” LIBRE officials take pains to say they are advocating policies, not specific candidates.

Garza said his group is focused on explaining conservative views. For instance, they talk about how a higher minimum wage might not be in the best interest of Latinos, because they believe it will hurt businesses and that there are less expensive ways for young Latinos to get health insurance than Obama’s health plan. Garza also said LIBRE advocates are getting millions of undocumented workers “out of the shadows” and into the legal system.
