More than 11,000 people showed up, some waiting five hours in the near 100-degree heat to get in. Mitt Romney won’t be able to match that enthusiasm among Nevada’s Latinos. But David Damore at UNLV says if Romney can peel away just 10 percent of Hispanic voters, that could make the difference in who wins Nevada.
