What kind of person typecasts the president by his socioeconomic group?????

My kind. The kind that reads. The kind that looks at policy preferences and compares them to other policy preferences, notices how they cluster, and puts the clusters in different binboxes.

The kind that does political sociology, like the Pew Center did. In broad terms, it works, just like personality typing works, and for similar reasons, and in similar ways: in broad, aggregate terms which nevertheless pretty well describe the electorate and the parties that work for their votes.

Any questions?

Exactly, applying broad aggregates to an individual ignores the atypical. It's silly.
