Dear Peter,

I guess that you are talking about "Hylland free riding",
rather than about "favourite betrayal".

See section 7 of my paper:


"In this context, Hylland free riding means that a voter
votes preferably for those of his favorite candidates who
are lower in the expected party list. (...) With this
strategy the stronger candidates get lower places than
they would have got otherwise, while the weaker candidates
get better places than they would have got otherwise;
therefore, the aim of this strategy is that the stronger
candidates get places that are still good enough and that
the weaker candidates get places that are just good enough
to get elected."
