More specifically, across 21 polls conducted since Obama took office in which Gallup measured both presidential and congressional job approval, 52% of Americans approved of Obama and 26% approved of Congress — a 26-point gap. George W. Bush’s average lead in approval over Congress during his eight years in office was 11 points, 49% to 38%. Bill Clinton had an average 18-point edge and Ronald Reagan a 14-point edge. By contrast, the elder George Bush’s average approval rating was 30 points higher than Congress’ approval rating in seven contemporaneous readings of the two measures conducted between 1990 and 1992.
