Before Dan Rather signed off March 9 after 24 years as a news anchor for CBS, conservative "netizens" already were cheering the man they believe led to the tidal wave of criticism that forced Rather to leave his post a year early: Atlanta attorney Harry W. MacDougald. MacDougald, 46, who has been with Atlanta's Womble Carlyle Sandridge & Rice PLLC since 2002, was the blogger "Buckhead" who first started a cascade of criticism about a report Rather aired Sept. 8 on CBS's "60 Minutes II" about President George W. Bush's Air National Guard service.
