Al Giordano wrote: "The partial recount did show that, out of 11,839 precincts recounted, 7,442 either had ballots missing or ballots above the number of people who had voted there. Had the trife annulled those precincts—a precedent set in its review of past state and municipal elections—López Obrador would have been declared president-elect. Instead, on August 28th the trife announced that it had annulled 237,736 votes, without specifying which or how many ballot boxes these came from. The result was to reduce Calderón's margin of victory by a mere 4,183 votes."
