New submitter nicoles writes with this quote from an AP report: "The Romney and Obama campaigns are spending heavily on television ads and other traditional tools to convey their messages. But strategists say the most important breakthrough this year is the campaigns' use of online data to raise money, share information and persuade supporters to vote. The practice, known as 'microtargeting,' has been a staple of product marketing. Now it's facing the greatest test of its political impact in the race for the White House. ... The Romney team spent nearly $1 million on digital consulting in April and Obama at least $300,000. ... Campaigns use microtargeting to identify potential supporters or donors using data gleaned from a range of sources, especially their Internet browsing history. A digital profile of each person is then created, allowing the campaigns to find them online and solicit them for money and support."
