FILE - In this Saturday, July 11, 2009 file photo, President Barack Obama and first lady Michelle Obama visit the La General Hospital in Accra, Ghana. President Barack Obama promised to visit his father's homeland of Kenya before the end of his presidency but of the 51 country visits Obama made in the last four years, America's first black president spent less than a day in sub-Saharan Africa. Obama is likely to spend more time in Africa in his second term, a presidential historian said. Freed of domestic campaign politics, second-term presidents can travel more in a continent that has less strategic importance than Europe and Asia. (AP Photo/Haraz N. Ghanbari, File)
