Dunkley byelection, page-582

Belyea scored a +.87 swing in her favour on the primary vote googs. so yeah..... her vote was an increase on Murphy's vote.

but who knows what individuals decided to vote elsewhere in disgust at Labs..... but clearly some of the PHONy/PUPpy and Lib Dem voters refused to vote Lib - they totalled more than 10% and the Libs only gained +6.8%, assuming that the real Lib vote was stable and not reduced.

so in fact it looks very much like it was the Libs lost some votes instead of gaining any through subterfuge deals with the aforesaid parties.
