To rule out the spuriousness of the second kind, you need a longitudinal panel data for individuals to show what comes first, union membership or voting Democratic. Such data may not be available for individual elections, but they surely must exist for general party preference. This is not really my field so I do not know what data are available, but can somebody with expertise in that field shed more light on this subject?
A data geek could work with the National Election Studies http://www.umich.edu/~nes/. They’re the best we’ve got, and they go back a long way.
