Not sure about her record, but the entry on Wikipedia says her mom works/worked at UNAM (one of the most famous Mexican universities). She was hired there and received some awards. Hard to say, but it has the smell of nepotism at the very least.

Her family mostly seems to associate with middle class directors, politicians and faculty. Definitely more privileged than the average Mexican, not much different than a US president. I’m guessing the policies will be what you’d expect with maybe a spin for the plebeians to think she’s on their side (again, much like the US).
