I have a lot of respect for her. She’s taken her career and maximized it with intelligence and creativity."― Carole King "The private citizen, beset by partisan appeals for the loan of his Public Opinion, will soon see, perhaps, that these appeals are not a compliment to his intelligence, but an imposition on his good nature and an insult to his sense of evidence."― Walter Lippmann
