Within days, that conference call catalyzed the kind of chain reaction among plugged-in activists that would replicate itself across the country, ultimately helping to propel Scott Brown into office. By December 28, Hennessy [a St. Louis Tea Party organizer] had blogged about the race, and within 24 hours, Brown's campaign manager e-mailed him about more ways to get involved—information that Hennessy then passed on to some 2,800 tea partiers in the St. Louis area, a significant number of whom joined the grassroots army that fundraised, phone-banked, and tweeted the unlikely senator to victory.
The sudden swelling of conservative activism and grassroots mobilization seemed to emerge out of nowhere, catching more than a few Democrats by surprise. Raising some $13 million in total contributions—with more than $1 million per day pouring in during the final days of the candidacy, many in small donations—Brown's campaign fed off the fervor that grassroots activists helped drum up across the nation. --
