Caroline Kennedy's supporters say she could raise tons of money as a senator, but when it comes to writing checks to New York Democrats, she's been largely AWOL.

This decade, other than a $1,000 donation to City Council Speaker Christine Quinn, the Camelot heiress has not financially supported any Democrat seeking city or state office in New York, records reveal.

Some say Kennedy, who is worth at least $100 million, missed an opportunity to curry favor among Democratic pols to establish herself as a serious political player as she lobbies Gov. Paterson for Hillary Clinton's Senate seat.

She has already been asked to explain a spotty Election Day voting record over the past 20 years.

"Voting is the minimum thing that you can do, and she hasn't done that. The next thing you can do is you could donate money, and she hasn't done that," said Doug Muzzio, professor of public affairs at Baruch College.

"It calls into question her commitment to politics and to government."

On the federal level, Kennedy doled out roughly $30,000 in the past decade, but Clinton was the only New Yorker to benefit.

Kennedy gave to Clinton's Senate and presidential campaigns. The former First Lady returned $2,300 of Kennedy's cash after she endorsed Barack Obama.

Stefan Friedman, Kennedy's spokesman, said she is a "lifelong member of the Democratic Party" and "has always supported New York Democratic elected officials and Democrats seeking office."

She "has also given her time and energy to many causes that New York Democrats hold dear."

In 2005, Kennedy did not publicly back Mayor Bloomberg's Democratic challenger, Fernando Ferrer. An aide contended she voted for Ferrer, though she had worked for Bloomberg.

In 2001, she attended an event for Democratic nominee Mark Green, but she did not speak on Green's behalf or provide financial support.

Her husband, Ed Schlossberg, has given to a number of New Yorkers, including Green, Clinton and Sen. Chuck Schumer.

Councilman John Liu (D-Queens), who is running for public advocate, calls Kennedy's Democratic credentials fuzzy.

"My comfort level with Caroline would be enhanced knowing she is truly upholding Democratic values or the values espoused in the Democratic national platform, which I'm not sure has been fully demonstrated yet," he said.
