Organization of American States Says Worried Over Presidential Vote Tally in Bolivia

According to the mission, the preliminary results on Sunday indicated that there would be a second round. The publishing of the results then stopped, when more than 80 percent of the vote was counted, and, when it was resumed a day later, the data showed a completely different trend.
"The OAS Mission expresses its deep concern and surprise at the drastic and hard-to-explain change in the trend of the preliminary results revealed after the closing of the polls," the mission said in a statement.
Incumbent President Evo Morales won 46.86 percent of the vote, the Bolivian El Deber newspaper reported earlier in the day citing data from the country’s Preliminary Election Results Transmission system.
Morales' rival Carlos Mesa, however, has refused to recognize the election results. Rallies in support of two main candidates have been held in several cities amid vote tallying.
