In Mexico, the party of populist candidate Andres Manuel Lopez Obrador is demanding a full, vote-by-vote recount in the country’s closest-ever presidential race. A preliminary count of the votes cast in Sunday’s election gave a slim lead to conservative candidate Felipe Calderon. But federal election officials acknowledged Tuesday that more than three million ballots–or eight percent of the total–remain uncounted. In the latest tally, Calderon leads Lopez Obrador by under one percentage point, meaning the race is still too close to call.
