I can't say I feel drawn to any of the polical parties and wouldn't trust a politician as far as I could throw them, but I always vote and end up choosing the one I feel is 'best of a bad bunch'. As GDB says, if you don't vote you can't complain when descisions are made which you don't like.
I am in one of the postal vote areas so had no excuse whatsoever not to vote. Just hope Royal Mail safely delivered my ballot paper, have had a few items of mail go astray lately and a shocking program a few weeks ago about the state of Royal Mail has left me even less confident!
The whole postal vote thing is a double edged sword. It will encourage more people to vote as lazy, apathetic people won't have to prise themselves away from their tv/Playstation/etc, but how can I be absolutely sure my ballot paper reaches its destination? At least when you vote at polling station you deliver your vote in person into the ballot box.
Like a fine wine, one gets better with age.
