Maybe an investigation of perjury committed against the State of Arizona when Obama signed an affidavit claiming to be Constitutionally eligible to be President...

Maybe you should read the applicable Arizona criminal statutes regarding perjury?

Did Obama sign a document attesting he was eligible for the ballot as a candidate for President?

If so, is there an image online?

There are available images of documents signed by Nancy Pelosi just after the 2008 Demo Convention.
