A whopping 64 percent of Republicans think it’s “probably true” that President Obama is hiding important information about his background and early life, including his possible birthplace, according to a new nationwide survey of registered voters from Fairleigh Dickinson University’s PublicMind project examining Americans’ belief in political conspiracy theories.

Belief in conspiracy theories is not unique to Republicans — 56 percent of Democrats believe in one of the four popular myths researchers asked about — but it is more common. Among registered GOPers, 75 percent said at least one of the four theories was likely true. Moreover, researchers noted: “Generally, the more people know about current events, the less likely they are to believe in conspiracy theories — but not among Republicans, where more knowledge leads to greater belief in political conspiracies.”
