Of course they should, and in a broad manner (i.e. total universe of interested parties), as your intitial post implies.
I managed some polling in my earlier life, and I still remember the little company in Beaverton, Oregon in 1980 that resisted our conculsions that the vast majoirty of the people who bought their products were not, in fact, elite athletes. Most of their customers bought their products because they looked "good" (in a fashion sense) and made them feel as if they were an athlete, even though they were not. I wonder what happened to that company........?
The USGA is stuck in the mores of the 1920's, but overly influenced by the big bucks mentality of the Naughties, and clueless of not only of who their customers/clientele are, but what they really, really want.
Polling could be a hurtful process for them (if done professionally), but hopefully they are big boys and can take their medicine. I'm not convinced of that yet, however.
