President Bush has arrived in Guatemala for the second-to-last stop of his five-nation tour of Latin America. He is meeting with Guatemalan President Oscar Berger for talks expected to be dominated by immigration and free trade issues.

Bush's visit to the region has been marked by mass protests and marches. In Brazil on Thursday, thirty thousand people took to the streets. The next day in Uruguay, some six thousand marched in the capital of Montevideo. In Bogota, police made one hundred twenty arrests when five thousand protesters marched just one mile from where Bush held talks with Colombian president Alvaro Uribe. Bush will travel to Mexico later today for the last leg of his tour.

While many analysts agree the president's trip is part of an effort to gain back influence in the region, the White House has sought to portray the tour as part of a humanitarian effort to address issues of poverty. Last week in Washington, President Bush spoke before the US Hispanic Chamber of Commerce.

President Bush speaking in Washington last week. In addition to the mass protests to his presence in the region, Bush has been dogged by Venezuelan President Hugo Chavez who is on a counter-tour of Latin America at the same time. In fact, Chavez has practically shadowed Bush since the beginning of his trip. When Bush was in Uruguay Friday, Chavez held a massive rally in neighboring Argentina. When Bush flew to Colombia, Chavez addressed thousands in Bolivia. While Bush is in Guatemala, Chavez is again close by in neighboring Nicaragua.

During a mass rally in Buenos Aires on Friday, the Venezuelan president launched a stinging attack on Bush who was in Uruguay, just thirty miles away across the River Plate.
