The wise voter needs first of all to find out if the seat is "safe".
Find out here.
If it is a safe seat, all votes apart from those for the incumbent are "wasted" in the sense that they do not get any representation in Parliament. There's our First Past the Post system (FPTP) for you. It is a crap system, and it has to go.
In a safe seat, then you might as well vote for your principles.The best signal to send is with a Green Party vote, because it signals your wish for radical reform of our political and economic system, reform that means your children and grandchildren will have a decent life. In other words, you get more bangs for your ballot with a Green vote.
If on the other hand you are in a marginal constituency, then I as a Green would strongly urge you to vote Green, if that option is open, since your vote will lever the winner to be more green in Parliament so as to win your vote back.
But I recognise that tactical voting is very appealing in a marginal seat, and here surely any thinking voter will wish to vote ABT (Anything But Tory) for the following reasons:
- They are infested with climate change deniers
- Their economic slash-and-burn policies will bring on a double dip recession
- They support the ridiculous FPTP system
- They would increase the Rich-Poor Gap.
If you have a choice between Labour and LibDem, then back the LibDem in the hope of getting a well-hung Parliament, with Vince Cable in the Treasury, and Proportional Representation well and truly on the menu.
All voters who care about democracy and political reform are recommended to murmur the words "First Past the Post Has Got To Go" to the clerks as they hand you your precious polling form.
I hope this is helpful.
