Not sure what you mean, a local friend of mine has a kid at one of those and other friend had a kid recently graduate from another. Yes, they are not huge targets for west coast kids but they do go. Agree with post above that region of origin rather than just income is probably a better indicator. (I would btw agree loosely that higher income might = more conservative but that can be relative - so here that would probably translate into what the classification calls “moderately liberal”)
