David Brooks' Patio Man is Derf's White Middle Class Surburban Man:
Unfortunately the archives at derfcity.com
are only 3 cartoons deep (but still worth checking for each week's new cartoon). Here are two from this year. The first was issued about six months ago, the second one is "current".
I am virtually certain that there was a cartoon with White Middle Class Surburban Man out on the patio
grilling up hamburgers, but can't find it on the web. White Middle Class Surburban Man isn't a bad persion, but is someone who is filled with the typical aspirations and anxieties you've read about, which make him favor Republicans. He's probably a Republican as well. Anyway, you get the point.
