We are divided between those who think with their heads and those who know with their heart. Consider Harriet Miers. If you think about Harriet Miers, of course her nomination is absurd. But the President didn't say he thought about his selection. He said this: "I know her heart." Notice how he said nothing about her brain? He didn't have to. He feels the truth about Harriet Miers.
