The Latest: Undecided voters key in Argentina

BUENOS AIRES, Argentina (AP) — The latest news as Argentina, Guatemala and Haiti hold votes for the presidency and Colombia for regional offices:

A polarized Argentina is selecting a successor to President Cristina Fernandez on Sunday, and undecided voters are key to the race.

Among those waiting to the last minute is Anai Roy, a 20-year-old college student. She says she still hasn't decided who to vote for as she goes into a polling place in Buenos Aires.

In her words, "I'll decide who I vote for when I'm inside."

Daniel Scioli is the anointed successor Fernandez and he goes into the election with about a 10 point lead in the polls.

To win, a candidate needs least 45 percent of the vote or 40 percent and a 10-point spread over the nearest competitor. Short of that, there will be a runoff in November between the top two candidates.
