The latest scion set to dip his toe into political waters is Ted Kennedy Jr., son of the late senator Edward M. Kennedy (D-Mass.) and nephew of President John F. Kennedy. According to local reports, Kennedy plans to announce his campaign for state senate in Connecticut on Tuesday. People with knowledge of Kennedy's plans told the Branford Seven, which first reported the news, that he will run for a seat being vacated by a retiring Democrat.

It wasn't that long ago that one of the most famous families in American political history had no representation in the nation's capital. Times have changed.

Caroline Kennedy, daughter of JFK, was sworn in as U.S. ambassador to Japan last fall. And Ted Kennedy's Jr.'s candidacy follows that of Joe Kennedy III, grandson of late senator Robert F. Kennedy (D-N.Y.), who ran for and won a congressional seat in 2012. Prior to that win, no Kennedys had been in major Washington office for the first time in more than six decades.

Ted Kennedy Jr., 52, co-founded the Marwood Group, an advisory firm focused on health-care. He was rumored as a possible candidate for his father's U.S. Senate seat after his death in 2009 and has also been considered a potential candidate for Senate in Connecticut, his home state. His brother Patrick J. Kennedy served in the U.S. House as a Democrat from Rhode Island from 1995 until 2011.

A outspoken advocate for people with disabilities, Ted Kennedy Jr. lost his leg because of cancer as a child. He lives with his family in Branford, Conn., which is east of New Haven.

In the future, more Kennedys might move into the political arena. As we noted in this space in 2010, there are a handful of others worth keeping an eye on in the coming years including Max Kennedy (son of RFK) and Anthony Shriver (JFK's nephew and the son of Eunice Kennedy Shriver and Sargent Shriver), to name just a couple.

Mark your calendars for 2044: That's when Edward Kennedy III (Ted Jr.'s son) plans to run for the U.S. Senate. Then 11, he announced his plans in 2009.

How's that for forward planning.
