Those are interesting questions you raise. To really answer them, I
think you need to find out if the "minor" parties have a tradition of
winning often in certain districts. If so, then perhaps those "minor"
parties are actually one of the two "major" parties in those particular
It would also be interesting to see how often those minor parties
function as spoilers. That is, how often do votes for those parties
cause the "greater of two evils" (from the perspective of their
supporters) to win?
If you or anyone else has time to pursue such research, the results
could be of interest with regard to the effectiveness of IRV in giving
minor parties a fair chance to win. It is often pointed out that
Australian IRV legislative elections provide somewhat more minor party
representation than we have in the US Congress. But if a comparable
effect occurs in British elections without IRV, maybe IRV is getting
undeserved credit in Australia.
