O'Donnell, who reteams with her former CBS This Morning colleague Gayle King as moderators for tonight's debate in South Carolina, explains how CBS News' approach will be different. "We have to get beyond Twitter headlines and talking points," she says. "We have to get into substance, because voters know what the substance is. Voters see multiple bills from doctors' visits or hospital visits that don't make any sense and they want an answer to that. Voters see that their taxes are different and they are not getting as much in pay—depending on what your bracket is."
