Rep. Michele Bachmann will be headlining September’s Taking America Back conference, an event that includes notable “birthers” Jerome Corsi, Aaron Klein, Joseph Farah and Alan Keyes. In fact, of the 15 speakers, at least 9 have expressed doubt that President Obama was born in the United States and is therefore an illegitimate president.

The event, to be held in Miami Sept. 16–18, offers attendees a choice between “the world of standards and morality, self-government and accountability to God or the world of tyranny and ever-changing moral codes enforced by government.” But while the conference website doesn’t include a schedule of topics yet, the lineup of speakers suggests it could focus on whether Obama is legitimately the president.

The 15 speakers include a Who’s Who of the “birther” movement, and many have ties to the conservative website WorldNetDaily, which is the event’s sponsor. That site’s managing editor and a conference speaker, David Kupelian, penned the piece, “Why I care about Obama eligibility issue.”

Kupelian’s boss, WND founder Farah, is also outspoken in his belief that Obama was not born in the United States. Farah has been instrumental in plugging Corsi’s book, Obama Nation, which questions the legality of an Obama presidency.

Other Farah employees who are speaking: Floyd Brown, who says there’s no proof Obama was born in the the country, and Aaron Klein, who has written a book doubting Obama’s legitimacy.

Also invited to address the confab is Gary DeMar, president of American Vision, a small religious right outfit who has doubts about Obama’s legitimacy.

“Whether Barack Obama was born in the United States is important, but even more important is for him to demonstrate his constitutional loyalty to a nation built on Christian principles,” DeMar wrote in 2009.

Keyes, the perennial Senate and presidential candidate, refuses to refer to Obama as “president” and has filed suit to gain access to Obama’s birth certificate.

Also speaking alongside Bachmann is former U.S. Rep. Tom Tancredo, who shares similar views with birthers, having once said, “Send Obama back to Kenya.”

Saturday Night Live alum and tea party activist Victoria Jackson told a rally in April, “Whether he has the birth certificate or not, he’s not an American.”

Only one speaker — Ann Coulter  — has the distinction of taking a firm public stance against “birtherism.” She called the movement’s proponents “cranks,” yet she’ll be sharing the stage in Florida with a line-up that includes a majority of so-called “cranks.”

As will Bachmann, who Farah described Sunday as “one of the leaders in calling for a repeal of Obamacare.”

“She’s a rock star, a principled, liberty-loving woman of conviction.,” he wrote. “It will be a treat to see her and hear her and interact with her in Miami.”
