“He’s done the best he could under the circumstances,” Carter said of Obama in an interviewed published on Thursday. “His major accomplishment was Obamacare, and the implementation of it now is questionable at best.”

What is Guinea worm disease?
Considered a neglected tropical disease, Guinea worm disease (dracunculiasis) is a parasitic infection caused by the nematode roundworm parasite Dracunculus medenisis. It is contracted when people consume water from stagnant sources contaminated with Guinea worm larvae. Inside a human's abdomen, Guinea worm larvae mate and female worms mature and grow. After about a year of incubation, the female Guinea worm, 1 meter long, creates an agonizingly painful lesion on the skin and slowly emerges from the body. Guinea worm sufferers may try to seek relief from the burning sensation caused by the emerging worm and immerse their limbs in water sources, but this contact with water stimulates the emerging worm to release its larvae into the water and begin the cycle of infection all over again.
Guinea worm is a particularly devastating disease that incapacitates people for extended periods of time, making them unable to care for themselves, work, grow food for their families, or attend school.

How widespread is the problem?
In 1986, the disease afflicted an estimated 3.5 million people a year in 21 countries in Africa and Asia. Today, thanks to the work of The Carter Center and its partners — including the countries themselves — the incidence of Guinea worm has been reduced by more than 99.99 percent to 126 cases in 2014.

I worked with a client in the 90's that was on his secret service detail.

What he had to say was quite surprising and not at all positive.

The man is not the personae.

And Jimmy Carter is a great man, but was a horrible president.
