I do often think that if people think things are bad under Labour they'll get a horrible shock if the Tories make it back in.
Elections in the UK are lost, not won. They're popularity contests, not policy contests.
I'm not sure how many people have any sense of policy at all. Voting seems to be punitive, which makes it easy to manipulate results with scare stories and resentment journalism.
Oddly enough it's not usually explained that voting for greasy wobble-chinned public school crooks isn't going to do working people any favours.
It doesn't help that both of the main parties are now run by greasy wobble-chinned public school crooks. I'd guess that only confuses people.
