1) The double bluff - don't bother voting
Don't give 'em the oxygen of legitimacy. Let it fall. One vote doesn't make any difference anyway, does it?
2) Spoil the ballot
This is a less nihilistic version of the above. No bad language, mind - don't oppress the tellers with obscenity, lest you lose the moral highground.
3) Vote UKIP
Don't know if they're standing my way. Ditto times two the Libertarians (these latter really should lose the bastard griffin - I've got a way better symbol for the party, but would they listen?)
4) Vote for some other minor party or independent
Maybe they'll have no chance of winning, but help them avoid losing their deposit.
5) Vote Tory
NOOOOOOOOO! I can't do it. I can't pretend they're the answer. I know the change they offer is an illusion - like a hit of smack on desolation row, we'll still be lying on the piss-stained mattress.
6) Vote Lib Dem
Fuck off. No way.
And that is all the options available.
