Mexico and Venezuela worked themselves into a diplomatic impasse this week, resulting in the recall of both countries' ambassadors. At the heart of the tit-for-tat which pulled the ambassadors and installed lower-ranking chargÃ© d'affairs were the opposing positions of Venezuelan President Hugo Chavez and Mexican President Vicente Fox at the OAS Summit in Argentina. Mr. Chavez along with Brazil and Argentina wanted nothing to do with the George Bush-led free trade position, while President Fox sided with the State. For his trouble Mr. Fox ended up being called "a puppy" of the U.S. government. It wasn't the first time a supporter of Prudent Bush earned a canine epithet. When British Prime Minster Tony Blair agreed to support the U.S. invasion of Iraq he was called "Bush's poodle" by the British media. Lap dogs aside, the Mexican election campaign continued to heat up with the PRI candidate for Mexico's presidential election (due next summer) calling the leftist front-running favourite, Andres Manuel Lopez Obrador, "another Hugo Chavez."
