So you do see the difference.
There's never been any question that Sarah Palin can read a hell of a speech. I was in the Excel center at the RNC when she spoke. The women can talk. After all she is a trained tv newsreader, reading other peoples words is what she learned to do in college.
But what role does she play in writing what comes out of her mouth?
Obama writes many if his own speeches himself, or at least is part of the team that does.
