Only true conspiracy nuts think that Mr. Obama is not a native born American Citizen. His birth record has been published on the internet. The Honolulu Star published his birth notice, the day after he was born.
The so called "Birthers" are idiots, with too much time on their hands. They could all do better with some hard manual labor.
I do not support Mr. Obama's positions on much of anything, but I do not attempt to claim that he is not a native born American Citizen.
