Andrew Sullivan has this comment on Palin's attempt to play the victim. The White House text of Obama's speech is here, and defences of Palin's video are here on right-winger David Frum's site.
Obama caught a mood, again. He invoked scripture, and spoke of the heroism of ordinary people. And this father of two young daughters was at his most passionate when he spoke of 9 year old Christina Green:
Imagine: here was a young girl who was just becoming aware of our democracy; just beginning to understand the obligations of citizenship; just starting to glimpse the fact that some day she too might play a part in shaping her nation's future... She was off to meet her congresswoman, someone she was sure was good and important and might be a role model.
She saw all this through the eyes of a child, undimmed by the cynicism or vitriol that we adults all too often just take for granted.
I want us to live up to her expectations. I want our democracy to be as good as she imagined it. All of us - we should do everything we can to make sure this country lives up to our children's expectations.
