Since the controversy began over Barack Obama's failure to conclusively demonstrate his eligibility to serve as president, legislators in at least 15 states have attempted to pass bills that would clarify how a candidate must prove his constitutional eligibility to occupy the Oval Office, and all but one have been stalled, vetoed or shot down.

As WND has reported, there exists virtually no mechanism in the U.S. for investigating whether or not a presidential candidate meets the Constitution's Article 2, Section 1, "natural-born citizen" requirement.

Last year, New Hampshire became the only state to successfully sign into law a bill clarifying eligibility requirements.

But New Hampshire's H.B. 1245, signed into law by Democratic Governor John Lynch, merely requires a statement under penalty of perjury that a candidate meets the qualification requirements of the U.S. Constitution, similar to what the political parties already send to states regarding their candidates.

Most of the efforts of at least 14 other states were launched in January, only to be tabled, ignored or killed by March. Montana's bill, which requires a candidate for president or vice president to submit a certified copy of his or her birth certificate to Montana's secretary of state, was ruled dead in committee on April 28 – the day after Obama produced his purported long-form birth certificate.

But Jerome Corsi, author of "Where's the Birth Certificate? The Case that Barack Obama Is Not Eligible to be President," says Americans shouldn't view Obama's release as the end of the issue.

"State legislators are being hoodwinked by the White House to think that just because Obama has released a long-form birth certificate, the question of his eligibility to be president is over," Corsi told WND.
