Public Policy Polling has conducted a nationwide survey in the US asking people about their belief in 20 various conspiracy theories.
A very interesting thing about this poll is that the respondents were also asked to answer which candidate they voted for in the latest US Presidental election. That means we can see which conspiracy theories are believed in to a greater extent by Right- and Left-wingers, respectively.
