Six weeks ago John McCain was leading Mr. Obama. But according to RealClearPolitics, as of yesterday Mr. Obama led in the national polls by just under 8% and in the Electoral College by 306 to 157 (a majority is 270). Throughout his campaign Mr. Obama has successfully presented himself as a careful and sensible person and was recently endorsed by Christopher Buckley, son of the late William F. Buckley, as having a "first-class temperament and a first-class intellect."
