Others (12.3 percent) said they were "not concerned," while 9.2 percent said the questions were not valid and 14.3 percent said Obama had met the requirements as a "natural born citizen." Another 8.5 percent said Obama had answered the questions to their satisfaction, while 6.3 percent said the requirements of the Constitution were simply outdated.

The WND/Wenzel survey was conducted June 6–10 using an automated telephone technology calling a random sampling of listed telephone numbers nationwide. The survey included 22 questions and carries a 95 percent confidence interval. It included 790 adult respondents. It carries a margin of error of +/– 3.5 percentage points.

Data from this survey also showed that a substantial majority – 56 percent – also wants Obama to release his educational records, which would yield more clues to his early life and citizenship. Among men, 62 percent said those school records should be released.

"These are questions that are not on the front pages right now, but they are far from going away – and people clearly want answers," said Wenzel. "As long as they go unanswered, they act like a low-grade fever that hampers everything Obama is attempting to do in office. And they could flare up at any time."
