I am assuming you mean proposed alternatives, as there are always other choices that could be made.
At the time, there were many different plans being proposed; but Palin fever at the time over-ran common sense.

Just out of curiosity, do you think that if Sarah had stayed Gov. that she would have recognized ACES as the mistake it was?
