In Mexico these days there is a veda electoral, or a ban on campaigning, ahead of the official campaign start.
Calderón and his party PAN should know better than to completely disrespect this, as well as other constitutional prohibitions of the president campaigning. Six years ago, Vicente Fox broke essentially every law in teh book and was strongly reprimanded by the courts for his interventions in the campaign. Calderón was then carried onward by an extremely dirty and dishonest campaign against AMLO.
Yet what does Calderón do? At a "private meeting" with 700 bankers, he presents the results of his own poll demonstrating that Josefina Vázquez Mota, the PAN's 2012 candidate, is allegedly only a few percentage points behind PRI's Enrique Peña Nieto and, with relish he relates, ahead of AMLO, his 2006 nemesis.
This politicking, aggravated by an extremely poor choice of timing, is really tasteless, and presents Calderón, already long criticized for his utter lack of any ability to listen to advice from others and his incessant stubborrness, as truly a little man, of no shame, and disrespectful of the presidential office as well as Mexico's democracy. It is nto worthy of a head of state.
