Republican presidential hopefuls want curbs on legal immigration

Republican 2016 presidential hopefuls Scott Walker and Rick Santorum are suggesting a potentially controversial way to boost Americans' job prospects: admit fewer legal immigrants into the United States. The notion, absent from presidential politics for at least 20 years, could help them tap into the frustrations of working-class voters who have struggled with stagnant wages and reduced job opportunities since the economic crisis of 2007-2009.
