People like him because he looks more up-to-date than Faulkner and if you look like your working then you must be.
Fitzgibbon on the other hand couldn't control the staff in his own office, who turned on him which fed his paranoia even more so.
People like Faulkner are dying out. Who wants hassle free, competent people working for them, they could take my job. Faulkners glasses are the perfect disguise, he won't ever be PM (he doesn't want to, even tho he is competent enough) because people think hes old fashioned and nerdy. Faulkner however probably keeps an eye on things and does what he can.
Everyone is vying for the power chair, and the boat could rock at anytime. Keeping Rudd around and in powerful positions keeps Smith controlled. Rudd apparently gave smith headaches (as Rudd would) when Rudd was PM and Smith was foreign minister. Make your enemies close, and keep your enemies enemies closer.
