The 20 Hillary Clinton supporters who sent House Speaker Nancy Pelosi a letter telling her to keep hands off the superdelegate fight warned ominously that they had been enthusiastic financial backers of the Democratic Party.
Now a campaign finance watchdog group has tallied up how enthusiastic: the letter-signers, along with their spouses, have contributed $23.6 million to Democrats since 1999, the Center for Responsive Politics said.
That largess includes $554,000 to Clinton's campaigns and political action committee -- 10 times what they gave to Barack Obama -- and nearly $3 million to the Democratic Congressional Campaign Committee, which helps Pelosi and other House members.
That committee played a key role in winning the majority in the House in 2006 that catapulted Pelosi into becoming the first female House speaker.
The letter writers were angered by Pelosi's statements that the superdelegates, the elected officials and party leaders, should not overturn the will of the people -- as measured by the tally of pledged delegates. Obama leads Clinton in that count, but Clinton argues that superdelegates were created to exercise independent judgment of who would be the best nominee.
