Everything I have read/seen/listened to about her indicates she is brilliant (including the opinions of her co-workers, watching speeches she has given etc). But intelligence and business aptitude are not synonymous. Pretty sure thats what I said. I wasn't backing off my opinion.
Truth be told, I was hoping for a more substantial answer, something that I could look at that unequivocally shows her "brilliance". The public statements of her's that I'm familiar with are pretty hum-drum.
