This photo taken Oct. 17, 2012 shows Cristina Aguilar, right, waiting with her granddaughter Enny Valle and Valle's husband Josh Valle, as other family members visit a petting zoo inside an amusement park, in Las Vegas. Aguilar, who works on an on-call basis as a hostess for the Circus Circus Casino buffet, and others like her have turned what was once a reliably conservative, largely-rural state into a key political battleground and a test case for whether Republicans can succeed without the support of a rapidly-growing Hispanic population.
