The meaning of " - - didn't mean what you said - - -" depends on what you said. Does this refer to some specific comment? -
everything he said about her? Without meaning to be partisan, this is really a cheap shot. It's a lawyer's trick. It's the
media [who are] dissing the American people by insincere tactics like this.
It's the
reporter who says, "You didn't mean what you said," not [Obama]. He's just fishing.
I completely agree with CJ's reply, by the way. There's just no point in trying to be specific about the meaning of something like this. I'm sure the reporter would be delighted if half the people who heard him thought he was calling Obama a liar.
Obviously the reporter would claim he meant, "How can you say she's capabable of being Secretary of State and incapable of being President?" It's nothing but a cheap insult.
