If there was any president who has endured so much grief while in office in the history of Ghana, it, arguably, should be the country's current leader, John Dramani Mahama.
Mahama, during both his first term as president and his current term, has experienced some unfortunate tragedies and lost a number of close relations, including his mother, as well as some very trusted political appointees.
The president, in his over 5 years of ruling the country, has had to declare 3 separate national days of mourning.
These deaths certainly have had some impact on his presidency.
