Voting for the conservatives because you don't like the way labour's performed is a bit like buying a different microwave cooker because you don't like the way tv dinners taste.
And shame on you wals, you're old enough to know how ****e the tories are, every bit as ****e as labour. The only difference is with Brown you know what you get, where as with Cameron people have this hope he's a gamble. He's really not.
Personally I reckon if you're goign to waste yoru vote, waste it on a minority. The only thing you can hope to get out of this election is a sense of superiority in that you voted for a party you genuinely believed in.
