Former Sen. Rick Santorum (R-PA) discussed his new book “Blue Collar Conservatives: Recommitting to an America That Works" Sunday on Face the Nation. The problem with Republicans is they are not unified, Santorum claimed: "we need to have a unified message that talks more about average working folks who are being left behind, by both parties in my opinion. The Democrats just want to throw money at them and Republicans aren't talking about them and how we're going to create opportunities for folks who are falling back as a result of President Obama's policies."
