I woke at 3am last night to watch the Hillary Clinton speech back home. It was broadcast here on cable, in my hotel room.
I lack the chops in public address criticism to talk much about it, but there is a dialogue of sorts on her sincerity going on here:

Does CBS News mean it? at Language Log Blog
The gist: the media have a Hillary narrative already, and very little she can do will force them to revise that narrative.
