Carter follows granddad

A grandson of Jimmy Carter is following the former President into politics with a run for the Georgia state Senate.

Democrat Jason Carter, a lawyer, says he will run for an Atlanta-area seat that's being vacated by President Barack Obama's nominee to be US Ambassador to Singapore.

If David Adelman is confirmed as ambassador next month, a special election could be held in March for his Senate seat.

Carter, 34, said his grandfather, once the Governor of Georgia, encouraged him to take the plunge.
