The birth-certificate business is not a uniquely conservative phenomenon; the allegation that Obama was born in Kenya seems to have originated with a Hillary Clinton supporter at a blog called The Blue State. Either way, this fantasy is not particularly widespread within the conservative movement, but it has attracted enough interest that it needs to be addressed.You should read the whole thing.
The fundamental fiction is that Obama has refused to release his “real” birth certificate. This is untrue. The document that Obama has made available is the document that Hawaiian authorities issue when they are asked for a birth certificate. There is no secondary document cloaked in darkness, only the state records that are used to generate birth certificates when they are requested.
