Have you ever seen the film The Dilemma? It's awful, but that's beside the point. There's a scene at the end, when the two best friends are fighting and one says to the other, pointing in his face and full of anger:
"It must have been really difficult for you, I can't even imagine, but don't ever keep a secret from me again."
And you realise: that's a very mature and reasonable response, and it just doesn't make for great TV.
Which brings me to Palin: why do you think everyone over here in the old world likes to talk about Palin and those crazy Americans that just might elect her? Because the "crazy Americans" won't elect her but the serious contenders just don't make for great TV. Why focus on a well-reasoned and intelligent Ron Paul when you can focus on Palin and get a laugh out of it.
By the way: look up Ron Paul.
