A video of Argentine President Cristina Fernandez de Kirchner dancing at a political rally in Buenos Aires took the country's Internet by storm Thursday. Video of the leader, filmed at a rally for her chosen successor Daniel Scioli, quickly went viral after she broke out into an improvised dance to a political rock anthem ahead of the general elections slated for Oct. 25.

The president, often known to her people as CFK or simply Cristina, has been known for her divisive politics and sometimes flamboyant style. She was elected in 2007 as the hand-picked successor of her husband, President Néstor Kirchner, who died in 2010. The Kirchners have ruled without interruption since 2003.

Term limits mandate that Kirchner step down after this term, and she has thrown her full support behind Scioli, who is the front-runner from her Front for Victory party. Scioli is expected to defeat challenger Mauricio Macri, according to early polls, though the contest may come down to a runoff in November.

At the Scioli rally in Buenos Aires, Kirchner broke out in the impromptu dance session. While she is dancing around the stage, Scioli points to the camera to show the president that her moves are being filmed, but she remains undaunted and carries on.

Kirchner's popularity has waned over the course of her two terms as the Argentine economy has stagnated and poverty levels have remained high. Macri is offering an alternative, center-right economic plan, which would include more free-market capitalism and less government intervention.
