I set myself up for this every time, but go and vote. All the arguments have been endlessly rehashed: all MPs are corrupt (no they’re not), your vote doesn’t count (yes it does), all parties are the same (no they’re not). It’s part of a franchise that people in the past fought for. Don’t let them down.
PS If you think all politicians are the same, and can’t tell the difference between Nick Griffin and Nick Clegg (to choose two names at random) you might think that you’re so delightfully cynical, but you’re not, you’re a plank.
