In recent weeks, in an office just off the Beltway in suburban Virginia, Rick Santorum?s mom-and-pop campaign for the presidency opened a national headquarters with less fanfare than Barack Obama regularly musters when christening a county field office.

Still, many top Santorum aides remain scattered across the country, working out of their homes and relying on teleconferences for their daily back-and-forth. ?We?re running a campaign the way people do business today,? Santorum adviser John Brabender recently told National Review. ?It?s not the classic, 1960s-style campaign.?
