According to Philip Wegmann of The Daily Signal:
On the campaign trail in 2008, Barack Obama promised to fundamentally transform the United States of America. After nearly eight years as president, he has delivered on one front by reshaping the federal judiciary.
That revolution has been comprehensive, dramatic, and under the radar.
When Obama entered the Oval Office, liberal judges controlled just one of the 13 circuits of the U.S. Court of Appeals. Fifty-five successful presidential nominations later, liberal majorities now control nine of those appeals benches, or 70 percent.
Outside of legal circles the transformation of the influential federal appeals courts has gone largely unnoticed, though.
