Luis Guillermo Solis, presidential candidate for the Citizens' Action Party, speaks to the media in San Jose February 3, 2014. Solis edged ahead in Costa Rica's presidential election on Sunday, riding a wave of disgust at government corruption to get within reach of wresting power from the centrist government in an April run-off. Solis, an academic who has never been elected to office, had a slim lead over ruling party candidate Johnny Araya despite trailing in pre-election polls and early vote returns.
