We already covered this for booze, but the research firm NMRPP has released a chart showing the political leanings (x-axis) and voter turnout (y-axis) of various major candy brands. Bubble size is proportional to the population of survey respondents who ate each type of candy.
Republicans are big on dark chocolate while Dems seem to favor fruit candies—this could have something to do with the fact that young voters lean heavily to the left. While it would be easy to imagine falling on either side of the political booze chart depending on your personal tastes, I'm comfortable saying that the Republican candies are unequivocally tastier than the Democrat candies. Butterfingers, like Captain Morgan's Spiced Rum, are bipartisan.
