"](CNN) - Caroline Kennedy, who spent most of her life looking to steer clear of the spotlight, is capping off a year of unusually public - and political - activity with interest in the Senate seat that would be vacated by Secretary of State-designate Hillary Clinton.
And her interest in that seat could mean the continuation of a Kennedy legacy in the Senate that began 56 years ago with the election of her father, John F. Kennedy, as the junior senator from Massachusetts.
Her uncle Edward has represented Massachusetts in the Senate for more than four decades. Her uncle Robert served as junior senator from New York from 1965 until he was assassinated in 1968.
"Remember, [Clinton's] seat in the Senate was once held by Robert Kennedy," CNN Senior Political Analyst Bill Schneider said Saturday. "Her other uncle, Ted Kennedy, is ill right now. If [New York Gov. David] Paterson appoints Caroline Kennedy to the Senate, it means there could be a Kennedy staying in the Senate for quite a long time."
