2005 Summit of the Americas in Argentina:
Thousands of demonstrators flooded the streets of this seaside resort Friday chanting “Get out Bush” as the U.S. president sought to promote free trade at a divided Summit of the Americas. Protests turned violent with about 1,000 people shattering shopfronts with clubs and pelting riot police with stones. … Demonstrators took to the streets hours before the summit started, shouting insults about Bush and chanting “Fascist Bush! You are the terrorist!” [AP, 11/4/05]
1998 Summit of the Americas in Chile:
At one point, Clinton walked in hazy sunshine down Gran Avenida, a busy commercial street lined with thousands of people, including schoolchildren in blue and white uniforms, many of them chanting “Clinton, Clinton.” A few bystanders chanted “Kennedy,” apparently in reference to the popular former U.S. president. [CNN, 4/16/98]
To be fair, there were also protesters when Clinton arrived in Chile, but we have yet to witness any indication that there is any popular support for President Bush in Argentina. Wonder why that might be.
