Not really books but did some undergrad research on the topic. http://stephendavies.org/writings/mitterederEtAl.pdf http://stephendavies.org/writings/mitterederEtAl.pdf We referred to it as "issue alignment" but its gone by other things, IIRC. Basically, in theory, one could end up supporting positions that would make 0 sense outside the context of "well, I support "X" cause "team green" supports "X." I've seen it happen often online, a lot less IRL.
