  9. “The Battle that Clinton didn’t expect”by E.J. Dionne, Washington Post, 04/03/08 page A19 … [Hillary] Clinton ran the last campaign of the 20th century while [Barack] Obama ran the first campaign of the 21st century. Galston argues that Clinton ran a first-rate version of the last century's campaign -- her fundraising by past standards was impressive. But Obama one-upped her by understanding the new possibilities of modern communications. It wasn't just that he outperformed Clinton by raising so much money online; he also exploited the social-networking sites (he built and has maintained a major web 2.0/social media presence) … [he] understood the interaction between virtual communities and real communities.
