Cocaine, pot, gay crushes and the white lover ambitious Barack Obama ditched to become President

AMBITIOUS Barack Obama was apparently so intent on becoming US President he considered dumping his white-skinned girlfriend.

Instead he continued seeing Sheila Miyoshi Jager for more than a year as he dated the future First Lady, Michelle.

Far from his successfully cultivated cool and sensitive image, a bombshell new biography paints Obama as a cocaine-snorting, pot-smoking lothario.

And it clams how, aged 25, Obama’s desire to reach the White House caused such a row between him and the then 22-year-old Sheila that their arguing and noisy make-up sex made a posh summer party “incredibly unpleasant”.

Sheila says she insisted Obama — then a local community organiser helping the poorly paid find homes and jobs — could become US president with a white girlfriend. It is said he was adamant they had to part.

Recalling the 1987 countryside get-together, a former pal of the couple says: “They went back and forth, having sex, screaming, yelling. That whole afternoon they were having sex and fighting.”

Sheila says in the biography that their years together were a “tumultuous love affair” full of passionate sex, labelling Barack “a very sexual/sensual person.”

But after supposedly sneaking a look at his private diaries only to uncover his writings about an ex, Sheila dumped him in 1988.

He met future wife Michelle the following year, while working at a Chicago law firm. But according to the biography he carried on seeing Sheila on and off well into 1990.

I always felt bad about cheating on Michelle with Barack... our relationship was a tragedy.

Sheila, now a college professor, said: “This is really, really sensitive stuff. We did not go our separate ways after 1988. I do not think Michelle knows.

“I always felt bad about it.”

She added: “Our relationship was a tragedy that has weighed and haunted my life.”

By the time Obama, 55, had married Michelle, 53, ­in October 1992, though, it was well and truly over.

The biography, by Pulitzer prize-winning historian David Garrow, also claims that pals at the fee-paying Occidental College in Los Angeles remember Obama as a “hardcore party animal” who was fond of magic mushrooms as an 18-year-old.

A former pal recalled the future President being “a mess” and experiencing a “big crisis” during one session on the hallucinogenic drug.

Obama has previously admitted in his 1995 autobiography Dreams From My Father to dabbling with both cannabis and cocaine, citing youthful experimentation.

But according to the new book, ­Rising Star, he was still getting “high on coke” aged 23 in 1985.

He would go back to his friend Sohale Siddiqi’s apartment where everyone “did several lines of cocaine, which added an edge to it all”, the book claims.

He had started smoking dope as a 16-year-old back in Hawaii.

On the Pacific island Barack, nicknamed Barry by his friends, was said to be in the cannabis abusing Choom Gang.

The danger of this illegal pastime was made all too obvious on one evening in 1978. After smoking with a group of pals the book claims they agreed to race a Toyota car against a VW van.

But when the Toyota that Obama was a passenger in didn’t reach the agreed finish point his friends started to worry.

One of the group, Tom Topolinski, went to look for them. He recalled: “We’re about halfway down and we see Barry running up the road, halfway in hysterics.”

A giggling Obama is said to have told him: “Kooks rolled the car. It’s upside down in the middle of the road.”

Fortunately for Kooks, who was the driver of the Toyota, he escaped with just a bloody nose.

Rather than calling for a tow truck the Choom Gang instead got more beer.

Topolinski said: “We were potheads. We loved our beer.”

It was at Occidental that Obama met his first serious girlfriend, fellow student Alex McNear.

One old poker buddy of Obama told Garrow: “He was really proud that he’d banged some super-hot blonde from a super-rich family.”

The book also reveals how he seduced one girlfriend, Genevieve Cook on their first date back in 1984, two weeks after meeting her at a party.

She says: “We went and talked in his bedroom. And then I spent the night. It all felt very inevitable.”

According to her diary “he neither came off as experienced or inexperienced” in the sack and grumbled: “It’s always in his bedroom without clothes on or reading papers in the living room”, and she worried that the young Obama just wanted her for “a warm time in bed”.
