Cape Town — American lobby groups advocating stronger United States government action to bring peace to Central and East Africa are calling on candidates in the U.S. presidential elections to give their views on the issue in their debates.

The Enough Project says in a blog post that Africa advocates want President Barack Obama and Governor Mitt Romney to discuss what it calls "the growing crisis in Sudan," as well as the regulation of conflict minerals in the Democratic Republic of Congo and the hunt for Lord's Resistance Army leader Joseph Kony in central Africa.

During the debate Tuesday night, the only Africa-related issue the candidates dealt with concerned the recent killing of the American ambassador to Libya.

Enough said on Tuesday that so far there had been only one mention of humanitarian intervention, in the vice presidential debate, when Romney running mate Paul Ryan had been asked for his party's criteria for humanitarian intervention.

The next and last debate before the November election, which will take place on Monday, October 22, focuses on foreign policy.

Enough called on supporters to back efforts by Act for Sudan and the anti-genocide campaign, STAND, to press debate moderators to ask candidates how they would prevent atrocities around the world and "how they propose to change U.S. policy to better prevent human rights abuses in Sudan."
