Do you have any evidence of any nature that is NOT the case?
Sure.
Time Magazine reports that they were married at Maui so searching the Honolulu papers may, or may not--where is Maui published, be fruitless.
Further, according to Obama's book and other sources, the marriage certificate is not found filed in Hawaii--Hawaii law requires the authority performing the marriage to file the certificate with the local authority in the jurisdiction that issues the license. Maybe that's Honolulu, even though the claim is they were married on Maui?
Whatever, we read in several places that the certificate cannot be found which to us implies the marriage wasn't performed where he says it was performed either.
I view looking at the newspaper Vital Statistics reports as the extra mile--Vital Statistics in Seattle used to publish the licenses as well as the certificate.
I just don't think they were married in Hawaii. Then you get them out of the Departure Lounge at HNL, on the way to Kenya--I don't see anywhere they might have gotten married until they get to Nairobi or Mombasa where the marriage is clearly legal under local law to everyone's satisfaction. Bet she might have had legal advice confirming that a marriage, made legal in Mobasa, is valid in the US for all purposes.
