On July 10, 2006, "Frontera NorteSur", reporting on an initial analysis by Civic Alliance, wrote: "In the Lopez Obrador strongholds, 312,450 more votes for senators than president were tallied, while in the pro-Calderon zones, 403,740 more votes for president than senators were tabulated." However, they do not specify which candidate seems to benefit from this. For example, in the PAN stronghold of Guanajuato, both candidates received almost exactly the same number of votes above their corresponding senatorial candidate, with López Obrador edging Calderón by 51,498 to 51,283
