TIM CARNEY: The IRS is deeply political — and very Democratic. “More than 75 percent of the campaign contributions from that office in the past three elections went to Democrats. In 2012, every donation traceable to employees at that office went to either President Obama or liberal Democratic Sen. Sherrod Brown of Ohio. The IRS officials whose names appear in the IG report are also Democrats with partisan histories. William Wilkins, IRS general counsel and one of the agency’s two explicitly political appointees, is a former Democratic congressional aide, lobbyist (clients included the Swiss Bankers Association), and Democratic donor. Joseph H. Grant, who ran the Tax Exempt and Government Entities Division that includes the Cincinnati office, is a former Democratic staffer on the House Ways & Means Committee.”
