Why didn't he have what changed? Either way, the "birthers" are stretching facts and falsifying them way too much. The fact is that there is no hard evidence. And beyond that, this conspiracy theory has hurt not only the "birthers" (as it should have) but many conservatives and Republicans because people tie the "birthers" in with them. Even if you believe this is true despite the lack of evidence, you are doing more harm than good for the American right at large.
