A new poll found that almost half of peopled who voted for Donald Trump believe that Hillary Clinton is involved in "Pizzagate," a conspiracy theory claiming—without evidence—that Clinton and her former campaign manager John Podesta ran a child sex ring out of a D.C. pizza restaurant.

According to a poll released Tuesday by The Economist and YouGov, nearly half of Trump supporters (46 percent) think there might be something to the Pizzagate conspiracy theories, which inspired a 28-year-old man to fire an assault rifle in a Washington, D.C. pizza shop earlier this month.

The poll, conducted between Dec. 17 and Dec. 20, found that 11 percent of Trump supporters think it's "definitely true" and 35 percent of Trump supporters think it's "probably true" that, as the poll phrased it, "Leaked email from some of Hillary Clinton’s campaign staffers contained code words for pedophilia, human trafficking and satanic ritual abuse—what some people refer to as 'Pizzagate.'"

On the other hand, 57 percent of Hillary Clinton voters think the conspiracy theory is definitely not true, though even 24 percent of Democrats say Pizzagate is "definitely" or "probably" true.

Overall, just 29 percent of Americans say the conspiracy is "definitely not true," and 34 percent of all Americans say it's "probably not true." But almost one in ten Americans (9 percent) still believe the conspiracy is "definitely true," and 29 percent say it's "probably true."

The poll looked into other conspiracy theories too.

Is it true that "Russia hacked the email of Democrats in order to increase the chance that Donald Trump would win the Presidential election?" While the CIA and the FBI concluded that it is true, Trump and his voters say otherwise. An astounding 80 percent think, like Trump, that the claim is "definitely" or "probably" not true. Overall, 52 percent of Americans think the claim is "definitely" or "probably true," compared to 48 percent who disagree.
