Is Dunkin Donuts Channeling Palin?

I just saw a Dunkin Donuts commercial that claimed that their coffee was preferred by more "hardworking Americans" in a blind taste test with Starbucks. You're obviously supposed to think that it's just plain better, but I couldn't help but notice the hardworking qualifier. Also, the people being polled in the commercial are a construction worker, taxi driver, and so on. Are they taking advantage of the Hillary Clinton/Sarah Palin distinction between "working" and "real" Americans and everyone else? (i.e., Starbucks drinking, argula eating Americans)
