Next month, Colombians will go to the polls and elect a new president or choose to remain with the current one. Though pundits and observers believe that the current president will remain in office, support for his campaign has shown signs of wavering and could affect election results.

President Juan Manuel Santos has been viewed as the frontrunner in the elections of May 25, according to Reuters. However, this lead could be lost soon if what a new poll has discovered is true. The poll conducted by Ipsos Napoleon Franco and published in the weekly magazine Semana found Santos losing his advantage.

The survey interviewed 1,208 people from April 21 to 23 and found that 23 percent backed the center-right incumbent, a percent point less than in a March poll and five less than a poll two months ago. To win, a candidate must gain more than 50 percent of the vote in May otherwise the two leading contenders will go on a runoff election set for June15.

Reuters reports that an incoherent campaign as well as his handling of both protests last year and peace negotiations between the government and FARC rebels have made voters skeptical and have shifted their support to the other candidates.

On the right-wing ticket is Oscar Ivan Zuluaga, member of the same party as the previous president, Alvaro Uribe. He is projected to get 15 percent of the vote, up from 9 percent last month. He opposes the current peace talks with FARC. Their rival, Enrique Penalosa of the Green Alliance (a non-environmental party, despite its name), has seen a rise to 11 percent of the vote from eight in March.

In preparations for the elections, 586,000 election observers have been chosen to oversee the event. According to Colombia Reports, the observers will monitor the presidential elections and try to prevent electoral fraud. Of the more than half a million chosen, 98,000 will be based in the capital city of Bogota.
