A new exposé book reveals the great hatred that exists between US President Barack Obama and his wife Michelle on one side, and former President Bill Clinton and his wife, former US Secretary of State Hillary Clinton, on the other.

Journalist Edward Klein cites numerous sources who overheard the two couples express their mutual hatred, and quotes them in his upcoming book "Blood Feud." Sections of the revealing text were published in the New York Post.

According to Klein, Obama has expressed that he may take back his promise to endorse Hillary in the 2016 presidential elections, and has suggested to the Clintons that Michelle, instead of Hillary, would make a good candidate.

According to the book Michelle would often sit with her adviser Valerie Jarrett while drinking Chardonnay during Hillary's stint as secretary of state, and referred to Hillary as "Hildebeest".

Clinton for his part had harsh words for Obama, responding after Hillary's loss to Obama in the 2008 Democratic nomination to allegations made by Obama that Bill was racist.

"I hate that man Obama more than any man I've ever met, more than any man who ever lived," Clinton reportedly told a friend after the allegations.

The book details how in September 2011 ahead of the 2012 election, Obama finally listened to his advisers' suggestion to get Clinton's support and invited Bill to play golf.

Bill reportedly told Hillary and friends at their Washington DC home Whitehaven "I’ve had two successors since I left the White House - Bush and Obama - and I’ve heard more from Bush, asking for my advice, than I’ve heard from Obama. I have no relationship with the president - none whatsoever."

"I really can’t stand the way Obama ­always seems to be hectoring when he talks to me," added Clinton according to sources who were present. "Sometimes we just stare at each other. It’s pretty damn awkward. Now we both have favors to ask each other, and it’s going to be very unpleasant. But I’ve got to get this guy to owe me and to be on our side."

In the golf game, Clinton reportedly compared their two presidencies, noting how under him America enjoyed eight years of prosperity, while Obama led the nation into some of its worst financial standing since the Great Depression of the 1930s.

Clinton then spoke about Hillary's qualifications for president in 2016, saying she would be "the most qualified, most experienced candidate, perhaps in history." Obama reportedly responded with words that surprised Clinton, saying "you know, Michelle would make a great presidential candidate, too."

"Bill was speechless. Was Barack comparing Michelle’s qualifications to Hillary’s? Bill said that if he hadn’t been on a mission to strike a deal with Barack, he might have stormed off the golf course then and there," reveals the book from its sources.

The disrespectful dinner

Then came a dinner between the couples last March 1, the day that $85 billion in budget cuts known as the “sequester” went into effect.

Bill questioned Obama's 2012 campaign organization, saying it should be joined to the Democratic National Committee, to which Obama only gave a "disparaging smile."

“You have to use your organization to aid the candidate in 2016,” Bill reportedly said to Obama, to which Obama replied with sarcasm "really?" The two reportedly raised their voices while debating the money for Obama's campaign and funds for the 2016 election campaign.

Then Obama began playing with his BlackBerry phone under the table as Clinton spoke, in a gesture seen as a rude snubbing of Clinton's words.

To change the subject, Hillary reportedly asked Obama "are you glad you won’t have to campaign again? You don’t seem to ­enjoy it.” Obama replied sharply "for a guy who doesn’t like it, I’ve done pretty well.”

“Well, I was glad to pitch in and help get you re-elected," said Bill, to which there was a long pause, after which Obama responded in a quiet voice "thanks."

Recently Clinton reportedly has been worrying in overheard conversations that Obama will not endorse Hillary, saying "(Obama)’s convinced himself he’s been a brilliant president, and wants to clone himself — to find his Mini-Me."

Speaking to his daughter Chelsea, Clinton reportedly said Obama is "hunting for someone to succeed him, and he believes the American people don’t want to vote for someone who’s been around for a long time. He thinks that your mother and I are what he calls ‘so 20th century.’ He’s looking for ­another Barack Obama."
