The Left demonizes David Koch and his brother Charles for their free-market views, their political donations, and the fact that they run a substantial energy company. Harry Reid has made a new career of it, calling them "un-American." But on the platform that morning were liberal Democrats Jerrold Nadler and Carolyn Maloney. Ms. Maloney was particularly gracious when she said, "There is hope for the world when Koch and I can agree on something. On this we agree 100 percent." - Now, contrast that with the arrogant, intolerant, petulant, radical-left environmentalist Robert F. Kennedy, Jr. Last week, at the People's Climate March in New York, he accused the Kochs of polluting our atmosphere.
