I bet that's not Hispanics exercising power, but other factors.
Hispanics made up more than two-thirds (67.9 percent) of California’s agricultural labor force, but only one-third (33.5 percent) of the state’s nonagricultural labor force in 2008.
Nearly all (95.2 percent) of California’s Hispanic agricultural workers identified Mexico as their country of origin. This compares to 82.0 percent of the Hispanic nonagricultural workforce.
In 2006, the most recent year for which CPS spoken language data are available, nearly half (49.4 percent) of California’s agricultural workforce identified Spanish as their only spoken language. In contrast, less than one out of every ten (9.3 percent) nonagricultural workers spoke only Spanish.
In 2008, Asians made up 12.6 percent of California’s nonagricultural labor force, but only 1.3 percent of the agricultural workforce. Blacks made up 6.1 percent of workers in the nonagricultural workforce, but only 1.0 percent of agricultural workers.
Agricultural workers tended to be less educated than nonagricultural workers. In 2008, nearly three-fifths (56.4 percent) of agricultural workers had not completed high school, compared to 14.5 percent of nonagricultural workers. In contrast, over three-fifths (62.9 percent) of nonagricultural workers had attended at least some college after high school, and one-third had attained a bachelor’s degree or higher. Among agricultural workers, one-quarter (25.4 percent) had attended at least some college after high school and only one out of every nine (11.1 percent) had attained a bachelor’s degree or higher.

In 2008, nearly half (48.6 percent) of California’s agricultural workers reported annual family income of less than $35,000. One out of every eight agricultural workers reported annual family income of less than $15,000. In contrast, a little over one out of every five (21.0 percent) nonagricultural workers reported annual family income of less than $35,000, and only about one in 20 (5.6 percent) reported annual family inco

Foreign-born noncitizen agricultural workers reported the lowest annual family income of any citizenship group, while native-born U.S. workers reported the highest. Foreign-born naturalized citizens tended to occupy the middle ground.

So, this actually supports what I'm saying.
