Mexico: Ruling party candidate has 'insurmountable lead'

Mexico’s ruling party’s Felipe Calderon had an insurmountable lead in today’s presidential vote count, but his leftist rival vowed to challenge the results in court, setting the stage for a long battle over who will lead the nation’s young democracy.

With 99.59% of the vote counted, Felipe Calderon would win even if all the remaining votes went to Andres Manuel Lopez Obrador of the Democratic Revolution Party.
