I'm a little surprised at some of these poll results. I believe "conspiracy theories" have grown in popularity and an increasing number of people enjoy discussing them even if they don't believe in them. Below are a few examples of the results.
20% of voters believe there is a link between childhood vaccines and autism, 51% do not
7% of voters think the moon landing was faked
13% of voters think Barack Obama is the anti-Christ, including 22% of Romney voters
