Costa Rica Votes in National Elections VOA News 07 February 2010 Photo: ASSOCIATED PRESS Costa Rica's National Liberation Party presidential candidate Laura Chinchilla waves to supporters after voting at a polling station in San Jose, Sunday, Feb. 7, 2010. Costa Ricans are voting in national elections Sunday, with polls indicating the country may elect its first female president. Laura Chinchilla is the frontrunner among seven candidates. She served as vice president under current President Oscar Arias. Chinchilla has promised to continue Mr. Arias' business-friendly policies and to take measures to curb rising crime. Her main challengers are Otto Guevara, who has called for tax cuts and adopting the U.S. dollar as currency, and economist Otton Solis, who wants to renegotiate the terms of the Central America Free Trade Agreement with the United States. A candidate must win at least 40 percent of the vote to avoid a runoff. Costa Ricans are also choosing a new legislature and municipal leaders.
