But Carter also confirmed there is a personal side to the backstory of the campaign video: he was especially motivated, he said, because of Romney’s frequent attacks on the presidency of his grandfather, including the GOP candidate’s comparisons to the “weak” foreign policy of Carter and Barack Obama.

“It gets under my skin — mostly the weakness on the foreign policy stuff,” Carter said. “I just think it’s ridiculous. I don’t like criticism of my family.”

Carter said he is currently unemployed and has not been paid for his work by the Obama campaign or any other political organization.
