54-year-old Fernandez is the first elected woman president in the country's history.
A local resident says he feels the result is fair.
"Particularly I'm very happy because justice has been done. That was the idea and I think the majority of Argentineans think the same way. I hope that the country grows and that we all have something to hope for."
Some analysts have attributed Fernandez's victory to her husband, whose government was credited with pulling the nation's economy out of the 2001-02 crisis.
