So here she's oversampling older residents who might have very different opinions than middle-aged or younger residents. So that doesn't make sense either. Ask 200 residents of her district whose names are chosen at random. Well, that seems reasonable. It doesn't seem like there's some chance that you somehow oversample one direction or another, but it's most likely to give a reasonably representative sample. And this is a pretty large sample size. So it's important to say what is the random process, where is she getting these names from, but this actually does seem reasonable.
