Don't be so naieve. The only thing conservative about our conservative party at the momement is the name. Blair frustrated his backbenchers for going to far to the right, and cameron is frustrating his by going too far to the left. You wouldn't vote for the democrats if they changed there name to the reaganite ultra conservative christian party of america unless you believed they actually stood for this things, which they don't in the same way I wouldn't vote for the conservatives over here (at the moment).
