SAN JOSE: Costa Ricans have elected their first woman president as the ruling party candidate won in a landslide after campaigning to continue free market policies in Central America’s most stable nation.

With most of the votes from Sunday’s election counted, Laura Chinchilla held a 22-point lead over her closest rival. Her 47 percent share of the vote was well beyond the 40 percent needed to avoid a run-off.

The 50-year-old protege of the current president, Nobel Peace Prize laureate Oscar Arias, promised to pursue the same economic policies that recently brought the country into a trade pact with the US and opened commerce with China.

“Today we are making history,” said Chinchilla, who will be the fifth Latin American woman to serve as president when she takes office in May. “The Costa Rican people have given me their confidence, and I will not betray it.”

The closest contender, Otton Solis of the Citizens Action Party, got 25 percent of the votes. He and the other main rival, Libertarian Otto Guevara, quickly conceded defeat.

It was unclear, however, whether Chinchilla’s National Liberation Party would gain a majority in congress.

The third-place candidate, Guevara, congratulated Chinchilla as “our president,” but he also pointed out the new political muscle of his tax-bashing Libertarian Movement Party. He won 21 percent of the vote.

Chinchilla, the mother of a teenage son, appealed both to Costa Ricans seeking a fresh face and those reluctant to risk the unknown.

As a female president, she would follow an increasingly common trend in many Latin American countries: Nicaragua, Panama, Chile and Argentina have all elected women as presidents.
