I think everybody in power has enormous egos. It may even be an advantage in that it enables a person to keep moving forward regardless of opposition (but that has a flip side, too). That said, I don't know how you measure somebody else's ego size, particular when you're not personally close to that person. Or their capacity for imagination, for that matter. But write about this, please. I'd be interested in how you do determine these things. What's the evidence. Yes, do write about this, please.
