President Barack Obama leaves behind his health-care barnstorming for a two-day meeting with Mexican President Felipe Calderón and Canadian Prime Minister Stephen Harper on Sunday to discuss the economy, climate change, and Mexico's drug problems. The North American leaders are meeting in Guadalajara, Mexico. One Mexican official told The Washington Post, "A great deal of this discussion will hinge on drugs and thugs. The fight that is taking place in Mexico today against drug trafficking is not going to be pretty, and it's not going to be simple, and it's not going to be done overnight." This is Obama's second trip to the country; he met with Calderón to discuss efforts to stop the drug trade in April. Also up for discussion is what kind of effort the countries are making to contain H1N1, (popularly known as swine flu), which is expected to return with a vengeance this fall.
