actually de genova has done a good job of representing Mexican public opinion.
http://www.washingtonpost.com/wp-dyn/articles/A24365-2003Apr3.html however, when you read de genova's writing its clear that what he wants is to break up the usa and either give parts to Mexico or have them form their own countries.
de genova is against the war because the war is igniting american patriotism and unity which tends to thwart the ambitions of the latins who are pushing for the reconquista agenda.
