The case of you being a Tory now. You say that you won't vote for them yet all you ever do is praise them, defend them, and slag off Labour.
Can I shed some light on their success? Of course.
The Labour Party haven't had a proper leader (I'm categorically not saying that he was a good leader) since Tony Blair. Brown was weak, the wrong Milliband was weak and Corbyn is far too divisive to be a party leader.
Put pre-Iraq Blair in charge now and it would be a completely different situation.
