Agreed! There's a Tory MP that needs to be removed from my constituency, and I'll cast my vote to whoever is best placed to make that happen. I'm in a historically Lib Dem area, whose vote share collapsed in 2015, and it's unclear whether they or Labour will be the best option come election time. I would rather vote Lib Dem, but if I've got to vote Labour in order to punish the Tory, then so be it.
