Personally, I nbelieve the "birther" movement is a designed distraction -- a distraction from the very real issue about whether Obama was actually born in Hawaii or not.
Once the emphasis changed from place-of-birth (and validity of the birth certificate) to the arcane definition of a "natural-born citizen", the movement went off the rails.
Whatever, the "birther" distraction has certainly been good for Obama's supporters.
That’s why I and other “Paleo birthers” walked away.
Many of us didn’t expect him to be removed from office, we just wanted it to be known so states would enact laws to require proof in the future. Unfortunately the same crowd got involved there and made it all about Obama which effectively killed legislation.
