Never vote for virually all parties, here.
Centrists (New Labour, Tory) are too in the pockets if big corpa and finance mogules, full of lies to suit their own interest, for me to vote for.
Right wingers UKIP BNP etc never, too too rudiculous and more liars.
Left wing such as Tusk not for me, too specific and better for single-policy pressure.
For years I've been with the Greens, as although I disagree with some of their wider policy, and I would have never been interested in joining a party I felt very stongly about *something they represent and was convinced to join.
Sorry for the essay! There is a point...
Corbyn has made me join Labour and so I will cross Labour off my never vote for list if he is leader.
