If you love Mexico, you can't vote for PAN?

"No one who loves Mexico can ally with or vote for the party of war, PAN."

This rather stunning slogan comes from AMLO's Movimiento de Regeneración Nacional (Morena), in a sharp attack on Calderón and PAN. All gloves have apparently come off, and there seem to remain no holds barred in AMLO's campaign for 2012, well under way: The most recent video, featured on the home page of AMLO's movement, makes the further claim that Calderón launched the military offensive against the drug gangs in order to legitimize his government, following the contested 2006 election, but also to to "the dirty work" for United States.

I am hard pressed to imagine how one can get any dirtier than this, which is moreover sadly ironic given that one of AMLO's main arguments in 2006 was the very dirty campaign from PAN: The pupil has now seemingly overcome the master.

In essence: If you vote for my opponent (or ally with them), you don't love your country.
