Ten years after Sam Nunn stepped off the US Senate's bright blue carpet for the last time, there are days the Georgia Democrat wishes he was still there.
He says he keeps up with what's going on and says there are times when he thinks he could make a contribution to a current debate.
Nunn was just 58 when he gave up his Senate seat.
He has not ruled out another round in politics, although he says he has no inclination to run for office.
He doesn't miss the fundraising, the scheduling uncertainty, and the pressure to keep up with the broad array of issues that senators must tackle.
And former colleagues he maintains contact with -- many of them
Republicans -- tell him the partisan lines he often worked across have only hardened over the years.
Now a 68 year old grandfather, Nunn still keeps a busy schedule, working full-time in a variety of capacities and traveling frequently between Atlanta and Washington.
He said he protects his weekends and relishes time with his wife, two children, and two grandchildren, including regular trips to a beach house on St. Simons Island.
Nunn was widely viewed as the Senate's foremost authority on foreign and military affairs at the end of his 24 year career, in which he served as an influential chairman of the Armed Services Committee.
He remains active in international affairs and is among a select group of former lawmakers who many current leaders look to for guidance.
