After her husband, former President Nestor Kirchner, passed away last year, her approval ratings skyrocketed. However, there is uncertainty about her re-election in the forthcoming presidential election, in October.
The defeat of her candidates in recent elections show that Kirchner still has work to do to win in the first round of elections.
