Obama relies heavily on ground effort

Obama camp relying heavily on ground effort Campaign borrowing from top GOP strategist Karl Rove's 2004 playbook

In 2004, Democrats watched as any chance of defeating President Bush slipped away in a wave of Republican turnout that exceeded even the goal-beating numbers that their own side had produced.

Four years later, Sen. Barack Obama's campaign intends to avoid a repeat by building an organization modeled in part on what Karl Rove used to engineer Bush's victory: a heavy reliance on local volunteers to pitch to their own neighbors, micro-targeting techniques to identify persuadable independents and Republicans using consumer data, and a focus on exurban and rural areas.

But in scale and ambition, the Obama organization goes beyond even what Rove built. The campaign has used its record-breaking fundraising to open more than 700 offices in more than a dozen battleground states, pay several thousand organizers and manage tens of thousands more volunteers.
