Travelling on the campaign trail with Salva Kiir, the president of Southern Sudan, is one of the most exhausting exercises I have ever been through.

Six flights - by both plane and helicopter - in less than 36 hours, and hundred of kilometers by car on bumpy road tracks, and under Sudan's blistering sun.

The president has been doing this for the past few weeks.

He is running a campaign in the bush, travelling to the most remote areas with a simple message: Vote for me and I will provide you with water, electricity, schools and hospitals.

People have been complaining that since the peace agreement was signed five years ago, little has been done to improve their lives. There has been growing resentment in the wake of what many see as a lack of proper governance. The government and the southern army - the SPLA - have been accused of corruption.

Still, Salva Kiir and his SPLM party are quite confident that they will remain in power. They are the symbol of the struggle against the north and the new found peace.

So until the referendum next January, people will give them a chance. After that, they will have to prove they can be a real government for all.
