The lack of engaging brain before opening the mouth I think is just about right.
He has had to backtrack on quite a few things, a little more experience and he should be Ok.
You have to know when to react quickly and get it right at the same time.
So far he is doing not to bad but he has not tightened the screws yet and that will bring the best or worst from him.
I still think it was ridicules of him to do away with the police guards while traveling I hope that does not come back to haunt him.
Apart from the odd little hiccup he seams to be doing Ok at the moment.
