Conservative activist Pam Geller now believes she has insight into the intimate details of President Barack Obama's parents' marriage.

The anti-Muslim Geller took up the cause of birtherism in a recent World Net Daily article where she claimed Obama was an illegitimate president because he was also an illegitimate child.

Her allegations were based on a recently released immigration file of President Obama's father, Barack Obama Sr.

"Stanley Ann Dunham was a white girl in a family way with a mixed-race child, desperate for legitimacy in a culture that condemned such behavior as abject immorality, and Barack Obama Sr. was a con man from Kenya desperate to stay in the USA," she wrote. "Was the marriage merely a business arrangement (she was 17 when she got pregnant)? Is that why it was so important to place the ads in the Hawaiian papers announcing the birth of the future president -- because his father was about to be deported?"

Geller continued: "Stanley Ann Dunham could not have been so savvy as to know that BHO I was a Muslim polygamist. Yet clearly, Barack Hussein Obama Sr., was never divorced from his first wife in Kenya."

"That would make the president illegitimate," she declared. "In 1787, illegitimate children had different rights. There is no way the founders of this great nation intended for an illegitimate child of a foreign bigamist to attain the highest, most powerful position in the new land."

World Net Daily editor Joseph Farah has worried that if Obama is allowed to serve as president then so-called "anchor babies" would also be eligible.

"Americans do not want illegal aliens to serve as presidents," he wrote. "That's not what the founders envisioned at all. But conceding to Obama's eligibility will open the door to American presidents who were 'anchor babies' -- children born of illegal aliens born on U.S. soil."

Birthers like Geller and Farah continue to make the argument that Obama is not a U.S. citizen in spite of the fact that he released his long-form birth certificate last week.

A recent ABC News/Washington Post poll found that the number of birthers had been cut in half in the last year.

As of May 1, only 10 percent of those polled believed that Obama was born outside the U.S., compared with 20 percent in April 2010. A full 70 percent acknowledged that the president was born in Hawaii, a 22 point swing from a year ago.

A Zogby interactive poll released Wednesday found that 30 percent of Republicans still do not believe the president is a U.S. citizen.
