Why not to clone a Jedi
I believe the reason why a Jedi wasn't cloned is that there would be no way to train these Jedi Clones. A Jedi Depends on the force, Without proper knowledge of the force or the proper training a force sensitive Jedi Clone is weaker then you and me. so unless the Cloners would have found a way to teach thousands of Padawans at the same time. the Clones whould be useless. and since the Cloners have no knowlegde of the force or Jedi training it would seem unlikely to me for them to train thousands of Padawans at the same time.
