The Center for Responsive Politics reports:

(W)hile it would be unseemly for the candidates to hand out thousands of dollars to primary voters, or to the delegates pledged to represent the will of those voters, elected officials who are superdelegates have received at least $890,000 from Obama and Clinton in the form of campaign contributions over the last three years…

Yet somehow, Sen. Hillary Clinton — who increasingly is looking like she needs superdelegates if she is to have a chance at the nomination — has only given $195,000 of that.  Sen. Barack Obama has given $694,000 to superdelegates from his political action committee, which is called… Hope Fund.  That’s right, Obama is the Man from Hope Fund.

The superdelegates say that any money flowing from the presidential candidates to their own campaigns hasn’t had any sort of influence on their decisions.

Yet the Center for Responsive Politics has found that campaign contributions have been a generally reliable predictor of whose side a superdelegate will take. In cases where superdelegates had received contributions from both Clinton and Obama, all seven elected officials who received more money from Clinton have committed to her. Thirty-four of the 43 superdelegates who received more money from Obama, or 79 percent, are backing him. In every case the Center found in which superdelegates received money from one candidate but not the other, the superdelegate is backing the candidate who gave them money. Four superdelegates who have already pledged received the same amount of contributions from both Clinton and Obama—and all committed to Clinton.

Rep. John Lewis just switched from Clinton to Obama.  A review of the CRP documents suggests that neither candidate donated to his campaigns in 2006 or 2008.
