You know the one about the apple not falling far from the tree?

December 20, 2007 -- Owe, brother!

Hillary Rodham Clinton's youngest sibling is a deadbeat dad who owes tens of thousands of dollars in child support to his politically connected ex, The Post has learned.

In a disclosure that could prove embarrassing for his sister, Anthony Rodham has stiffed his former wife, Nicole Boxer, out of $75,000 in child support, as well as $55,000 in alimony, a source close to the case said.

Including interest and various fees and expenses, the presidential candidate's brother now owes Boxer - the daughter of Sen. Barbara Boxer (D-Calif.) - more than $158,000, the source said.

The revelation that Rodham is delinquent with his payments won't be a welcome development for Hillary Clinton, coming as the too-close-to-call battle for the Democratic presidential nomination reaches a fevered pitch and with the first votes to be cast in Iowa in exactly two weeks.

Barbara Boxer has not endorsed a candidate in the race.

Nicole Boxer received judgments from a Washington judge ordering Rodham to pay up earlier this year, but the cash-strapped business consultant has yet to fork over the hefty sums.

"He has consistently been a deadbeat dad when it comes to paying child support and spousal support, despite the courts telling him over and over again that he must meet his obligations," a source close to Nicole Boxer said.

Rodham's lawyer, Gwendolyn Jo Carlberg, said she would "not comment on the veracity of any figures that are the subject of private and confidential settlement negotiations, as this is a personal, family matter and is under seal." She did say her client "fully intends to honor the judgment."

Nicole Boxer's lawyer could not be reached for comment.

Rodham, 53, married Boxer in the White House Rose Garden in 1994, when his brother-in-law, Bill Clinton, was president.

The couple had a son, Zachary, two years later, but the political union came to an end in 2000.

Fights over child support soon followed - at one point in 2002, Nicole charged that her ex hadn't paid anything in six months.

The latest support strife has been going on most of this past year, and Carlberg said her client has been trying to settle their differences in and out of court.

She said a Superior Court judge ruled against Rodham earlier this year.

"He strongly disagreed with the ruling, and so did I," she said. "We appealed the decision, and Mr. Rodham did not prevail."

That final ruling was in October.

Carlberg said she "sent a settlement letter to Ms. Boxer's attorney a few weeks ago for structured payment. As of today, we have not received a reply."

The Nicole Boxer source blasted Rodham's settlement offers as "just another dodge from meeting his obligations to his former wife and son while he lives in his fancy Washington town house" with his new wife, whom he married in 2005.

A former insurance salesman, prison guard and private eye, Rodham has been a headache for the former and possibly future first family before.

He and his brother Hugh embarrassed the Clintons in 1999 with a politically perilous plan to import hazelnuts from the former Soviet republic of Georgia.

He also became a figure in the "Pardongate" scandal, when it was revealed that he lobbied Bill Clinton to pardon two embezzlers.

Rodham made headlines again shortly after his split from Nicole, when he was attacked at his family cottage in the Berkshires by a man who claimed he saw Rodham having sex with his girlfriend.

Rodham later testified that he "might have" smoked pot with the woman.

Considering what a white trash family she comes from it is no wonder that Hillary was attracted to a piece of Arkansas trailer trash like Bill. She probably felt like she had finally found her true home amid the sleaze of Hot Springs and Little Rock.

I can't believe that the nation is seriously considering electing another liberal sack of garbage from that sh!t-hole.
