At the Citadel military college in South Carolina, Mitt Romney made a neo-conservative foreign policy speech today. He called for reversing cuts in the Pentagon and increasing military spending, and suggested that President Obama had surrendered America's role as being the strongest nation on earth. Romney is still regarded as the Republican front-runner, but polls show he lacks enough conservative backing to make him the sure nominee. Last July, Herman Cain said that Romney's Mormon religion was no problem for him, but that it would be for southern evangelical Christians. Even though Cain apologized, did he have a point? And if Romney got the GOP nomination, would his religion turn off secular Democrats and Independents? We hear different opinions on Romney's prospects and ask why Cain has suddenly shot up in public opinion polls. What about Rick Perry?
