Senator Hillary Rodham Clinton was gracious in her full-throated endorsement of Senator Barack Obama. But that does not mean all is forgiven by others in the Clinton universe.

For proof, look no further than Doug Band, chief gatekeeper to former President Bill Clinton.

Mr. Band keeps close track of the past allies and beneficiaries of the Clintons who supported Mr. Obama’s campaign, three Clinton associates and campaign officials said. Indeed, he is widely known as a member of the Clinton inner circle whose memory is particularly acute on the matter of who has been there for the couple — and who has not.

“The Clintons get hundreds of requests for favors every week,” said Terry McAuliffe, the chairman of Mrs. Clinton’s presidential campaign. “Clearly, the people you’re going to do stuff for in the future are the people who have been there for you.”

Philippe Reines, a spokesman for both Clintons, said neither kept any specific catalog of those believed to have wronged them. “There is no list,” Mr. Reines said.

The lists maintained by supporters tend to be less formal documents than spoken diatribes, with offenders’ names spat forth in rants, gripe sessions and post-mortems.

Several names and entities are common among various list makers. The lineup invariably begins with A-list members like Gov. Bill Richardson of New Mexico; Representative James E. Clyburn of South Carolina, the House Democratic whip; Gregory B. Craig, Mr. Clinton’s lawyer in his impeachment and trial; David Axelrod, Mr. Obama’s chief strategist; Senator Claire McCaskill of Missouri; and several Kennedys. Some members of the Democratic Party’s rules committee, the state of Iowa and the caucus system in general are also near the top.

If you truly believe that there is no list then you are, sorry to say, a very naive person. As the old say goes, “paybacks are a bitch”!  Take that anyway you would like!
