Nah, this is smart. The President doesn't need to preach to the choir right now. We're already primed and pumped. Guaranteed there is no way he loses a single voter tonight, because we already know what he's about, and we already know that the media is actively abusive and dishonest.

That makes this a win only situation. After this there will only be two types of viewer - those who didn't change their minds, and those that changed their minds to vote for President Trump.
