Mr. Hodges, I understood you were proposing to use some single-winner method applied to all candidates (across political parties) of a riding to produce a proportional method. This is something I advocate for a long time. Markus showed me I was wrong, and you were only proposing to rank candidates among the same party. Some parts of my previous answer to you may thus be irrelevant.
