ANALYSIS-Goodwill gives Obama added leverage in Africa

* Oil, anti-terrorism seen as U.S. priorities in Africa

* Ghana rewarded for democratic power transfer

* China's influence grows rapidly

DAKAR, July 9 (Reuters) - Goodwill for President Barack Obama could give the United States a little extra leverage to push good governance in Africa as well as in its priorities of securing energy supplies and fighting terrorism.

As the first black U.S. president, Obama is assured of an African hero's welcome in Ghana at the weekend.

But the United States still faces growing competition for influence from China and other emerging economic powers seeking resources and markets -- and putting less emphasis on matters such as governance that Obama is likely to stress in Ghana.

"Obama is not going to have it easy meeting these expectations because democracy in Africa is not the best," said Vladimir Antwi-Danso at the University of Ghana's Legon Centre for International Affairs.
