With two-thirds of the vote counted and 43.6% of it in her favour, Cristina Fernandez de Kirchner has claimed victory against Elisa Carrio, with his comparatively pipsqueak 22.6% share.
Of course, claiming victory and actually being victorious are two different things, but it looks like Kirchner is well on her way to succeeding her husband, the incumbent president Nestor Kirchner.
Cristina Fernandez de Kirchner will be Argentina's first female president. She has already drawn comparisons to Eva Perón, also known as Evita, who was the wife of Argentina's former president Juan Perón.
The challenge ahead that Cristina Fernandez de Kirchner faces is to deal with the growing doubt among the populace over official funny-business statistics indicating inflation is under control.
Like her husband, she prescribes to centre-left policies. She has been a senator for the province of Buenos Aires.
