No what to make of it? A person is born into some family or another. Dubya has to make a tough decision, or rather a whole bunch of decisions, and to make the right ones broaden his vision (perhaps -- I think it is already pretty broad).
But brought in with the current President is all the baggage of his life and what can he make of it, how does it help him, how does it hobble him? No one can say how they would have themselves performed in his stead. Ridgeway is too mocking of him and his mind.
There is a awful lot of inertia to the actions of needed remedies in that baggage, I think. Yet Dubya is as fine and fast on his feet to fix things to right as any I have seen.
Ridgeway can't be ignored, his critiques have some validity. I think Dubya can rise up to the challenge, and frankly Dubya has usually beat my own expectations and even been far shrewder in making calls on things. Not that I'm anybody, but still, Dubya has been full of pleasant surprises in my view.
