ID cards, why won't they just die?

While he won't be writing it Tony Blair has today said that ID Cards will be in Labour's next election manifesto. Everybody knows that they will not work. Even the civil servants that are going to have to implement the damn things know that they will not work. The biometric passport that was the original excuse as to why they where needed has already been hacked, it's design being "Brain dead", so expect the supposedly flawlessly secure ID Cards to fall equally quickly should they ever get out in the wild.

Why won't ID Cards just die? Nothing else for it. Stake, cross, holy water. Time to go to work.
