OPINION - I have that thought today because of Alaska Gov. Sarah Palin's announcement that she is resigning. I have no idea if she is, as NPR's Politics blog so nicely headlines it, "Retreating Or Reloading." Politicians are human. If you prick them, they will bleed. If you pet them, they'll lick your hand. They're filled with anxieties, contradictions and duplicities, but I wonder what groups, including journalists, salespeople, hammer dulcimer makers or Franciscan priests, are not. - NPR.org
