Trucks on the streets are encouraging people to vote but in earthquake-ravaged Haiti, this will be no ordinary presidential election.
More than eight months after the disaster, the capital Port-au-Prince is struggling to rise again.
The UN has stressed the importance of a credible poll in November.
A televised debate between candidates on Saturday was interrupted by blackouts. And some fear election politics itself could distract from and even undermine the reconstruction process.
Up to 300,00 people were killed in the earthquake
and more than a million left homeless. The international aid community has faced criticism that efforts to clear rubble and relocate surivors from makeshift camps have been slow to materialise. And the presidential palace still lies in ruins.
