Article Photos: Sin City's pull puts state of Nevada in play



  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.
