BRISTOL, Va. -- To rousing applause, Barack Obama formally announced this afternoon that the Democratic National Committee will follow his lead and begin refusing donations from registered lobbyists and special-interest political action committees.

"They do not fund my campaign," the presumptive Democratic nominee told a small-town southwest Virginia crowd, after delivering a standard refrain that blames drug and insurance interests for blocking universal health care. "They will not fund our party. And they will not drown out the voices of the American people when I'm President of the United States."

Well, at least not on the presidential level.

The Obama campaign confirms that two other arms of the national party - the Democratic Congressional Campaign Committee and the Democratic Senatorial Campaign Committee - will continue to accept lobby and PAC money this election.

Barack Obama campaigned on a pledge to change Washington, vowing to upend the K Street lobbying culture he encountered when he joined the U.S. Senate.

But more than a dozen members of President-elect Obama's fast-growing transition team have worked as federally registered lobbyists within the past four years. They include former lobbyists for the nation's trial lawyers association, mortgage giant Fannie Mae, drug companies such as Amgen, high-tech firms such as Microsoft, labor unions and the liberal advocacy group Center for American Progress.
