I would note, too, that 1) college educated suburbs are much more college educated than they were 30-40 years ago, matching the overall trend towards higher educational attainment nationally. The number of post-baccalaureate degree holders is also growing faster than the number of baccalaureate degree holders. 30 years ago, it would not be difficult to find a state school grad and his non-degreed wife living in Evanston or Winnetka...that's probably not very true anymore. 2) White college grads have gotten substantially more secular over the past 30-40 years.
well this begs the question - have white college grads themselves changed? Because if they voted as they once did - DuPage would probably vote republican. Is it possible that white college grads have gone from looking like this:
