One of the fail safes for me is that whilst our ex MP is still involved with the local labour party, then labour will never again get my vote, (in fact if they were to lock him away in a sanatorium and throw away the key, I wouldn't vote for labour ever again because the whole party seems built on his type of attitude).
So, if the only alternative While I'm on This one way trip to hell would be a guy that likes his party to party a little, I think I can live with that far more easily than labours attempts at dicktatorship.
