We think our colleagues at PolitiFact.com, who also dug into some of these loopy theories put it pretty well: "It is possible that Obama conspired his way to the precipice of the world’s biggest job, involving a vast network of people and government agencies over decades of lies. Anything’s possible. But step back and look at the overwhelming evidence to the contrary and your sense of what’s reasonable has to take over."
In fact, the conspiracy would need to be even deeper than our colleagues realized. In late July, a researcher looking to dig up dirt on Obama instead found a birth announcement that had been published in the Honolulu Advertiser on Sunday, Aug. 13, 1961:
Obama’s birth announcement
The announcement was posted by a pro-Hillary Clinton blogger who grudgingly concluded that Obama "likely" was born Aug. 4, 1961 in Honolulu.
Of course, it’s distantly possible that Obama’s grandparents may have planted the announcement just in case their grandson needed to prove his U.S. citizenship in order to run for president someday. We suggest that those who choose to go down that path should first equip themselves with a high-quality tinfoil hat. The evidence is clear: Barack Obama was born in the U.S.A.
