Of all the nutty rumors, baseless conspiracy theories and sheer disinformation that we’ve dealt with at FactCheck.org during campaign 2008, perhaps the goofiest is the claim that Barack Obama is not a “natural-born citizen” and therefore not eligible to be president under the constitution.
This claim was first advanced by diehard Hillary Clinton supporters as her campaign for the party’s nomination faded, and has enjoyed a revival among John McCain’s partisans as he fell substantially behind Obama in public opinion polls.
