Marketing

To what degree might it be possible to use characterizations of market segments that were intended for commercial/product purposes for reaching and moving a given audience toward a more progressive position over time? As a corollary, to what degree might it be possible to use characterizations of market segments that were intended for get out the vote efforts for reaching and moving a given audience toward a more progressive position over time? I ask, because segmentation research is expensive, and we may be able to economize if we can build upon what's already been done.
