Astute concision.
To be a leader one has to effectively socialize, empathize and engage with those who are better than you and those who are worse than you. John Kerry cannot do this because he is better than everyone else. He was the same in Vietnam. The Swifties despise the arrogant Yale college boy they knew who disobeyed orders, who did as he pleased. That's why the first Swift Boat advertisement said:
"I know John Kerry. John Kerry cannot be trusted"
