IMO, these proposed laws should compel candidates to provide the state AG with special powers of attorney (duly signed and notarized in the style required by that state) which would then be used BY THE STATE to obtain certified copies of birth certificates directly. None of this "provided by the campaign staff" baloney.
Basically, the states should be seeking a way to verify eligibility directly from the state offices where the candidates' vital records are recorded. That's about as clean a system as I think it possible to obtain.
An excellent point (and idea). You should forward it to legislators sponsoring such law.
