A section in the proposed platform of the Republican Party of Iowa requires candidates to prove they are a natural born citizen of the United States, according to Radio Iowa.

Don Racheter, chairman of the Iowa GOP’s 2012 platform committee, told Radio Iowa that the section was directly aimed at President Barack Obama.

"There are many Republicans who feel that Barack Obama is not a ‘natural born citizen’ because his father was not an American when he was born and, therefore, feel that according to the Constitution he’s not qualified to be president, should not have been allowed to be elected by the Electoral College or even nominated by the Democratic Party in 2008, so this is an election year," Racheter said. "It’s a shot at him."

Obama has been dogged by questions about his eligibility to serve as President of the United States since 2008. Many of the so-called "birthers" believe Obama was born in Kenya in 1961 and that his birth certificate was faked in order to make him eligible for the presidency.

In an attempt to quiet the "birther" conspiracies, Obama released his long-form birth certificate last year. It confirmed what his other birth certificate released in 2008 said: the president was born in Honolulu, Hawaii on August 4, 1961.

Other "birthers" claim that Obama is not a "natural born citizen" because his father was a British subject. But those claims are contradicted by a Congressional Research Service report on the subject.

"The constitutional history, the nearly unanimous consensus of legal and constitutional scholars,and the consistent, relevant case law thus indicate that every child born in and subject to the jurisdiction of the United States (that is, not children of diplomatic personnel representing a foreign nation or military troops in hostile occupation), is a native born U.S. citizen and thus a 'natural born Citizen' eligible to be President under the qualifications clause of the Constitution, regardless of the nationality or citizenship of one’s parents," the reported stated.

Hawaii officials have repeatedly confirmed Obama’s citizenship and judges around the nation have consistently dismissed “birther” lawsuits against Obama’s right to be president as frivolous.
