In 2013 there was a poll about conspiracy theories. They provide contingency tables that show relationships between beliefs in various conspiracy theories and voting in 2012 US presidential election, political ideology, gender, party affiliation, race and age. Looking at these tables it seems that belief in JFK conspiracy is somewhat similar across the political spectrum, and, maybe surprisingly, it was very liberal people (and not very conservative ones) who were most likely to agree with the official explanation. Obviously, grouping all JFK conspiracy theories into one option loses a lot of information, as liberals and conservatives would probably differ in which ones they find the most appealing. Moreover, neither liberals, nor conservatives are homogeneous groups, and this poll does not show differences among the subgroups (e.g. geographical or some other kind) that might exist.
