If there was solid evidence that Obama was born somewhere else, it would be worth investigating further. For example:
1. Is there any evidence Ann Dunham flew to Kenya?
2. Is there any evidence Ann Dunham gave birth to Barack Obama in Kenya or anywhere else?
3. Is there any evidence, upon returning to Hawaii, that she submitted a bogus claim of birth?
You can’t give credence to some crazy old grandmother back in the Kenyan serengeti and then, with a straight face, say that the entire State Government of Hawaii is in on the scam.
Oh yes they can. There is no level of craziness someone wed to a conspiracy theory won't stoop to. Once a person becomes emotionally invested in a conspiracy theory there is absolutely nothing you can do to convince them they are wrong. Human nature is what it is. Even otherwise rational, intelligent and thoughtful people can fall prey to this sort of thinking.
