But the main opposition groups are now pulling out after Omar al-Bashir, Sudan's president, dismissed their demands to postpone the elections which are scheduled for April 11.
The major opposition parties, including the Justice and Equality Movement and the Sudan People's Liberation Movement (SPLM), say they are concerned about massive electoral fraud, exclusion of voters and violence.
For his part, al-Bashir has threatened to scuttle a referendum on south Sudan's independence if the SPLM follows through with its election boycott.
That could undermine efforts to consolidate the 2005 peace deal between the ruling National Congress Party and the SPLM which ended the civil war.
On Monday's show we ask: Will Sudan slip into another cycle of violence if its political process fails?
Discussing that will be Sayed el-Khatib, a former Khartoum government spokesperson, and Ezekiel Lol Gatkuoth, the head of mission of the government of south Sudan in the US.
