Drudge posted the headline quickly before linking to the poll, and later sent readers to Rasmussen's lighthearted poll on conspiracy theories.
According to the Rasmussen poll, 23 percent of Americans said the conspiracy theory that Obama was not born in the U.S. was true, and 17 percent said they were unsure. Sixty percent rejected the theory.
Rasmussen included a few other "best-known conspiracy theories" in its poll.
Only 45 percent of Americans rejected the theory that President John F. Kennedy was killed by more than one shooter. And 24 percent said they believe the U.S. government knew about the Sept. 11, 2001 terrorist attack before it happened.
Rasmussen surveyed 1,000 Americans via phone July 16-17 with a margin of error plus or minus three percentage points.
