B+?

Mr. Obama has not governed as the centrist, deficit-fighting, bipartisan consensus builder he promised to be. And his promise to embody a new kind of politics—free of finger-pointing, pettiness and spin—was a mirage. He has cheapened his office with needless attacks on his predecessor…

Mr. Obama may believe, as he told Oprah Winfrey in a recent interview, that he deserves a “solid B+” for his first year in office, but the American people beg to differ. A presidency that started with so much promise is receiving unprecedentedly low grades from the country that elected him. He’s earned them.
