extent he has changed, i think there is a weight on his that there wasn't 2015, orlked to him in even in 2011 when he was first talking about running for this office. then he was very much someone playing in this new space. he was experimenting with what he could do in politics. he was coming up with ideas as he went. has internalized the gravity of the position he's in. it doesn't mean he's not tweeting. it does mean that he's aware, of where his provocations could lead. interesting to see how much he reins himself in. the reality is he has advisers around him who are regularly telling him to do things differently than he chooses to he often doesn't follow their advice. it will be interesting to see he chooses when he becomes president, when he takes that office, how to adjust his performance. michele: you mentioned his tweeting. he's taken to twitter again this week. people wonder if this improvisational communication just that, is it improvisational or is there a strategy behind it? in some way?ic is there a logic behind what he's doing when he takes to twitter, often late at night
