She's definitely had a makeover for a more sophisticated look, far from the school teacher look she had when she first became known to us in 2015.
My money is on her becoming president at some time in the future. Perhaps Macri will nominate her as his running mate in the general elections next year or even bow out himself, allowing her to run for president.
She comes across as having a steel backbone and I'm wondering if she'd make a more popular president than Macri.
