This photo taken Oct. 17, 2012 shows Cristina Aguilar lifting her one-month-old great granddaughter Adelina Valle out of her carrier after getting home from a day of canvassing the streets for President Barack Obama, 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.
