Globetrotting former US President Jimmy Carter says he's found strong support for Barack Obama during his recent trips to Africa and Asia. Carter has stopped short of formally endorsing Obama as the Democratic Party's presidential nominee and would not be drawn on the issue in a meeting with reporters Monday. However, Carter noted that his children, grandchildren and their spouses back the Illinois senator who is competing with New York Sen. Hillary Clinton for the nomination. Carter says Obama was the favorite in his travels to Ghana, Nigeria and Nepal. He says "world opinion is strongly supportive of Obama, that's all we hear."
