Check out this demographic'ing wizardry used "to cherry-pick prospective Republicans who lived in majority Democratic neighborhoods":
Republican firms, including TargetPoint Consultants and National Media Inc., delved into commercial databases that pinpointed consumer buying patterns and television-watching habits to unearth such information as Coors beer and bourbon drinkers skewing Republican, brandy and cognac drinkers tilting Democratic; college football TV viewers were more Republican than those who watch professional football; viewers of Fox News were overwhelmingly committed to vote for Bush; homes with telephone caller ID tended to be Republican; people interested in gambling, fashion and theater tended to be Democratic.
Surveys of people on these consumer data lists were then used to determine "anger points" (late-term abortion, trial lawyer fees, estate taxes) that coincided with the Bush agenda for as many as 32 categories of voters, each identifiable by income, magazine subscriptions, favorite television shows and other "flags." Merging this data, in turn, enabled those running direct mail, precinct walking and phone bank programs to target each voter with a tailored message.
