Steven Miller has been fired as Acting Director of the Internal Revenue Service, but he was back on Capitol Hill today, testifying before the Senate Finance Committee, in one of three unrelated "scandals" that could threaten Barack Obama's second-term agenda. In addition to the IRS, there's the Tea Party, the Justice Department and reporters' phone records, and talking points about the killing of diplomats in Benghazi. With the President's approval ratings over 50 percent and holding, many questions remain to be answered. Does the public care? Is there evidence of wrong-doing? Will Republicans overplay their hand? What's the role of the news media? Will there be an impact on action on Obamacare, the minimum wage, sequester or immigration reform?
