Typical, chip on shoulder, anti-Conservative, narrow minded, rubbish.
Think of this way, what if there were a larger group of people than you think who wanted to vote for the Green candidate? What is that candidate made themselves better known with their campaign? What if you voted for the person you wanted, as you know, you're supposed to do and then what if more people did that? You never know, that candidate may get in!? That's the beauty of politics, sometimes a candidate with a decent campaign will surprise a few people, but they've got to have the backing of their supporters.
You support that candidate, vote for them.
