Someone’s going to have to produce a Canadian or Washington state birth certificate to counter the Hawaii Certificate. Producing a "document" is a nothing deal nowadays. It proves nothing without some form of corroboration. For example, I put absolutely no stock in this document, but it "looks" official.
How did the mother’s signature get on the original birth certificate if she was in Washington state or Canada?
How did my doctor's signature get on MY birth certificate 5 years after the fact? The state PUT IT THERE, when they created my new replacement birth certificate. (I'm adopted.)
Stanley Ann was Obama's mother, so she very likely signed his birth documentation at some point. All they have to do is copy it from that original signature, which they do in the case of Replacement birth certificates.
The state of Hawaii is standing by the following:
(Stanley) Ann Dunham signed the Obama Certificate of Live Birth on August 7, 1961. Dr. David A. Sinclair signed it as attending physician for Kapi’olani Maternity and Gynecological Hospital on August 8, 1961 and Vickie Lee registered the birth for the state of Hawaii on August 8, 1961. The Hawaii Health Bureau forwarded the vital statistics information of that birth to the Honolulu Advertiser and Honolulu Star-Bulliten for publication in their August 13, 1961 and August 14, 1961 editions in those newspapers’ Vital Statistics sections along with Marriages and Deaths. The birth was also recorded by the Health Bureau in the 1961 Index File of all Hawaii births.
I am not saying that the information above is impossible to impeach, I’m only saying that it is a high bar to impeach that information 50 years later.
