CARACAS, (Reuters) – While many Venezuelans went to the beach to enjoy the Carnival holiday, thousands of anti-government demonstrators marched in the capital yesterday, trying to keep up the momentum from weeks of protests demanding President Nicolas Maduro resign. There are no signs that Maduro, who says the protests are part of a U.S.-backed coup plot, could be ousted in a Ukraine-style overthrow despite widespread discontent with soaring inflation and chronic product shortages. Government leaders have urged Venezuelans to skip the protests and make their traditional trips to the beach during the Carnival holiday. State television was filled with images of packed beaches and smiling holidaymakers.
