Jason Carter in The New York Times 2010s

On Crime: No ban on the death penalty

So it goes in what may be the nation's most awkward legacy campaign. Political families--from the Roosevelts to the Kennedys, Bushes and Clintons--have long been a part of American politics. Carter's bid to unseat Gov. Nathan Deal, the Republican incumbent, is testing the strength and durability of the Carter name in Georgia, a red state that Democrats hope to turn blue. But it is also a test of something more: a deep bond between a 38-year-old grandson and an 89-year-old grandfather.

On Foreign Policy: Declares his powerful connection to Israel

The former president's views on Israel are not the only ones to make his grandson squirm. Of the elder Carter's call to ban the death penalty, his grandson said, "I love my grandfather, but we disagree."

The elder Mr. Carter has plunged into his grandson's campaign. "He got elected governor of Georgia by shaking 600,000 hands," the younger Mr. Carter said. "That's what he would tell you: 'You've got to go to the grocery store and shake everybody's hand.' "

On Principles & Values: Grandfather Jimmy Carter participates in grandson's campaign

Senator Carter is the son of Jack Carter, the eldest of Jimmy and Rosalynn's four children. Like his grandfather, he is seeking the governorship after just four years in the State Senate.

"He wants it both ways," said one supporter of Gov. Deal. "He wants his granddaddy's help with contributors, but when it comes to the issues, he distances himself. My guess is if his last name were Jones, you and I might not be having this conversation."
