Byline:JANIE LORBER AND ERIC LIPTON c.2010 New York Times News Service WASHINGTON -- In the days leading up to the Delaware primary, Sal Russo hosted a radio fund-raiser, organized a political rally and pressed the case with reporters that Christine O'Donnell was the Tea Party's choice for the U.S. Senate. He also set off what he calls a 'money bomb,' pouring at least $250,000 into TV and other advertisements promoting the little-known candidate. With O'Donnell's upset victory in the Republican primary on Tuesday, Russo, the chief strategist behind an upstart group called the Tea Party Express, had racked up another win. But in becoming one of the movement's most successful players by helping Tea Party favorites oust incumbents or trounce rivals in four states, Russo is also fast becoming among the most divisive. Unlike many of the newly energized outsiders who have embraced Tea Party ideals, Russo, 63, is a longtime Republican operative who got his start as an aide to Ronald Reagan and later raised money for a string of other politicians, including former Gov. George E. Pataki of New York. His history and spending practices have prompted some former employees and other Tea Party activists to question whether he is committed to, or merely exploiting, their cause. Russo's group, based in California, is now the single biggest independent supporter of Tea Party candidates, raising more than $5.2 million in donations since January 2009, according to federal records. But at least $3 million of that total has since been paid to Russo's political consulting firm or to one controlled by his wife, according to federal records. While most of that money passed through the firms to cover advertising and other expenses, that kind of self-dealing raises red flags about possible lax oversight and excessive fees for the firms, campaign finance experts said. 'They are the classic top-down organization run by GOP consultants, and it is the antithesis of what the Tea Party movement is about,' said Mark Meckler, a national spokesman for Tea Party Patriots, a coalition of grass-roots organizations that does not endorse or contribute to candidates. Russo's group is also under attack from Republican Party leaders in Delaware, who have accused the Tea Party Express of improperly collaborating with O'Donnell' s campaign. Federal laws allow political action committees to support candidates independently, but they are not permitted to coordinate their spending with campaigns. Russo dismisses all the criticism, saying he and his group have done nothing wrong. The Delaware party leaders are simply poor losers, he says, and his Tea Party critics are envious of his success.
