Nevada Provides Next Test for US Presidential Candidates Carolyn Presutti LAS VEGAS, NEVADA - Mary Rooney wears a button on her pink sweatshirt that reads, "I am woman, watch me vote." Rooney arrived for early caucus voting Monday in Las Vegas, Nevada, to vote for her favorite Democratic presidential candidate. The retiree insists that the results of the earlier caucus and primary contests in Iowa and New Hampshire, respectively, that catapulted Vermont Senator Bernie Sanders to the head of the pack do not speak for the nation. "Nevada is more diverse and more like America," said Rooney, who voted for Massachusetts Senator Elizabeth Warren as her first choice and included Minnesota Senator Amy Klobuchar among her top four choices. Rooney's son is a member of the United Auto Workers union. She was shocked to see a line wrapped around the United Auto Workers union office when she arrived for early caucus voting. The polls opened Saturday in Nevada and closed Tuesday, with more than 36,000 residents taking advantage of the state's first-time offer of early voting. The formal caucuses will take place throughout the state Saturday afternoon. .
