How close was Panama’s last Presidential race?

I heard it was by a landslide, does anyone know how close it actually was?

President Martinelli easily beat out Balbina Herrera in the 2009 elections, getting more than 60% of the votes cast, compared to her 36%—it was the biggest margin since the late ‘80s.  It is estimated President Martinelli’s presidential campaign cost about $35 million.  After winning the election, President Martinelli said he would defend an “economía libre” (free economy), including trade agreements with the United States, making Panama “el mejor lugar de Latinoamérica para hacer negocios” (the best Latin American country in which to do business).
