I have two stellar ones: Tom Kean & Brendan Byrne.
My Republican parents knew them both quite well, and liked them. I once attended a political conference in Cherry Hill with Tom Kean in the early '70s. In fact, he rode in my car, and we later both got a little sloshed together at a Harvey Wallbanger punch bowl at a reception, I think for Essex County Republicans. (I still believe somebody spiked it, I've never hallucinated from drinking before or since) But a very nice guy in person, very affable.
Strictly speaking I really wasn't supposed to be at a political event, attending college but still an Army Officer in civilian attire. But my parents encouraged me to go, they wanted me to forget about the Army and take up something "respectable" with a brighter future, like politics.
They were mortified that I had chosen the Army, only begrudgingly accepting my career when I became a Field Grade Officer, and realized I wasn't gonna change. But at that time they wanted me to have these connections, and in fact Byrne's Administration, though Democratic, offered me the position of Executive Director of New Jersey Network (public TV affiliated with PBS, later including radio) in 1980 when I returned from Germany.
They wanted me to initially operate out of Newark, where I would also wear the hat of TV Station Manager to get their newest studio up to speed (until then they only had Trenton). Stupid me, I turned it down so I could take my scheduled Officer Advanced Course and continue my military career. Then Tom Kean became Governor while I was on the staff at the US Army MP School, and I told my parents to stop fishing for political appointments for me, I wasn't gonna take them, I was happy where I was.
But that's the networking and influence that goes on in these things, at least in New Jersey, no doubt how Christie formed a good part of his own staff. And why he ended up with the results he's got now. If somebody like ME could be offered these things in the past, based solely on family connections, imagine the others working for him.
