The miracle of the ballots

Greg Palast writes for The Guardian (reprinted in Buzzflash):

The precinct-by-precinct returns were quite otherworldly. I used to teach statistics and what I saw in Mexico would have stumped my brightest students. Here's the conundrum: The nation's tens of thousands of polling stations report to the capital in random order after the polls close. Therefore, statistically, you'd expect the results to remain roughly unchanged as vote totals come in. As expected, AMLO was ahead of the right-wing candidate Calderon all night by an unchanging margin -- until after midnight. Suddenly, precincts began reporting wins for Calderon of five to one, the ten to one, then as polling nearly ended, of one-hundred to one. How odd. I checked my concerns with Professor Victor Romero of Mexico's National University who concluded that the reported results must have been a "miracle." As he put it, a "religious event," but a statistical impossibility. There were two explanations, said the professor: either the Lord was fixing the outcome or operatives of the ruling party were cranking in a massive number of ballots when they realized their man was about to lose.
