Former Argentine President Nestor Kirchner gestures as he arrives for a ceremony at the Casa Rosada Government Palace in Buenos Aires, June 17, 2008. Kirchner's wife Argentine President Cristina Fernandez's image deteriorated further in June as a nasty dispute with the farm sector entered its fourth month, according to a poll released on Tuesday. Her center-left government raised soy export taxes in mid-March, sparking farmer protests that have caused occasional food and fuel shortages. REUTERS/Marcos Brindicci (ARGENTINA)
