I apologize to Palin fans – this is actually a post about Lance Armstrong.  This Slate article makes a point about Armstrong that has struck me too:

Five months into Armstrong’s comeback, his athletic career has taken a positive turn: He’s just a fraction of a second off the lead in the Tour de France. His bizarre, histrionic behavior while off the bike, though, leaves one to wonder whether this guy is cut out for public life. Lance actually shares a few traits with Sarah Palin. They both react to any criticism with extreme defensiveness. They demonize their enemies while at the same time cultivating nonstop melodramas that keep them in the news. And while they both periodically issue petulant threats to quit, you get the funny feeling that neither one is going away anytime soon.

Before he retired, Armstrong used to come under attack.  He responded aggressively and yet in a controlled manner.  Perhaps there were media advisors.  Twitter seems to have released him for all constraints.   I hope twitty Jeff keeps himself under control.
