Haiti's presidential candidates are wrapping up their campaigns with loud, musical rallies. The major candidates are focusing their last-ditch efforts on the capital, Port-au-Prince, where more than a third of voters live. Nineteen candidates seeking the post in Sunday's balloting include ex-prime ministers, an ex-first lady, popular musician and garment factory owner. Outgoing President Rene Preval backs the head of the state-run construction company. The victor expects to oversee billions of dollars in foreign aid pledged after the Jan. 12 earthquake. He or she will also inherit joblessness, millions of quake-displaced citizens and a cholera epidemic expected to sicken 400,000 people. The list of 4.7 million registered voters includes many who died in the quake.
