Ex-politicians on the speaking trail?

Disgraced Conn. Governor John Rowland delivers motivational speeches around the country, telling his story that spirituality and religion have made him both “aware” and contrite. And former Alaskan governor Sarah Palin makes the rounds as well, often to the tune of $100,000 per speaking engagement! She is buoyed by the Tea Party Movement and other politically disenfranchised…  So… do former politicians make great communicators? No longer campaigning for our vote at the polls, do they have messages that enlighten? What’s the draw?
