Mexico's electoral tribunal TEPJF's (specifically its regional branch in Toluca) annulled PRI's victory in the mayoral race held past month in the state capital Morelia.
The argument: The illegal live television coverage of campaign closing of gubernatorial candidate Fausto Vallejo, and a boxing match where one of the fighters wore shorts with PRI's logo - forbidden according to electoral rules.
Officially, difference between PRI's Wilfrido Lázaro Medina and PAN's Marko Cortés Mendoza was only 2000 votes, or 119, 941 to 122, 258. Now a rematch will need to be held.
PRI, as one may imagine, is not happy about the verdict, and strongly suggests pressure from president Calderón , who it notably took a month to recognize the victory of Vallejo as governor.
Now, given TEPJF's reasoning, the PRD demands annulling the entire state elections, pointing to narco interference but also that of President Calderón himself. PAN also demands the governor election cancelled. I really doubt that, as it would be quite extraordinary, but then again, we live in extraordinary times.
There is already one problem: Morelia will for sure need to run new elections, but they are not cheap - and the state electoral institute does not have money for another extraordinary election.
(On another note, the Archdiocese of Morelia comes out pretty strongly against the recent governments of the state, particularly that of Lázaro Cárdenas Batel (2001-07), essentially accusing him of not having been prepared at all for the job and exercised it poorly).
