I don't make a decision based on individual issues. I am a socialist, so I look for a party that has strong support for the welfare state, is committed to improving the living standards of ordinary people and particularly of the poor, and opposes discrimination in all forms. If they were pro-nationalisation, that would be the cherry on top but that seems to be a step too far for the major political parties.
When Jeremy Corbyn was leader of Labour, there was a political party which reflected my views. Well, part of it did, but there was a large faction in the PLP doing everything they could to undermine that vision. Now we're back to a Labour Party that wouldn't recognise socialism if the latter jumped up and bit it, and I shall have to vote for them because at least they aren't the Tories.
I have voted for the Greens a couple of times but they don't often stand here, and I have voted tactically for the Lib Dems once or twice. Never doing that again, after Nick Clegg presented us with a progressive manifesto and then went back on it all by hooking up with Cameron, just to get into power. I did like his ideas, though, before he abandoned them.
It's all academical, anyway, as I have lived all my life in a Tory stronghold. My vote has never made the slightest difference and our MP is useless. I emailed him about the Triple Lock and about more financial support to reduce the waiting lists for cancer operations, and he never bothered to answer.
