Microtargeting

Microtargeting is the use by political parties and election campaigns of direct marketing datamining techniques that involve predictive market segmentation (aka cluster analysis). It is used by United States Republican and Democratic political parties and candidates to track individual voters and identify potential supporters.

They then use various means of communication—direct mail, phone calls, home visits, television, radio, web advertising, email, text messaging, etc.—to communicate with voters, crafting messages to build support for fundraising, campaign events, volunteering, and eventually to turn them out to the polls on election day. Microtargeting's tactics rely on transmitting a tailored message to a subgroup of the electorate on the basis of unique information about that subgroup.

Although some of the tactics of microtargeting had been used in California since 1992, it really started to be used nationally only in 2004. In that year, Karl Rove, along with Blaise Hazelwood at the Republican National Committee, used it to reach voters in 18 states that George W. Bush's reelection campaign was not able to reach by other means. The results were greater contacts with likely Bush voters. For example, in Iowa the campaign was able to reach 92% of eventual Bush voters (compared to 50% in 2000) and in Florida it was able to reach 84% (compared to 50% in 2000). Much of this pioneering work was done by Alex Gage and his firm, TargetPoint Consulting.
