SAN JOSE (Reuters) - Conservative Christian singer Fabricio Alvarado Munoz is in a tight race with his centre-left ruling party rival ahead of a run-off on Sunday to decide Costa Rica's presidential election, their campaigns driven by duelling views on gay rights.Alvarado Munoz, a 43-year-old former television host, shot to the top of the polls in January soon after denouncing a ruling by the Inter-American Court of Human Rights that month which called for the legalization of same-sex marriage.
He went on to win the first round ahead of ruling party candidate Carlos Alvarado Quesada, 38, a former minister also known for writing fiction and his student rock band.
