Have we heard this before?

This is the 19th debate that Clinton and Obama have participated in and there are only so many questions to be asked and only so many answers to give.
So prepared are the two, that they even know the arguments the others will make..
In this case, when dealing with the economy, Obama laid out many of his proposals and then cut himself short by saying, "Sen. Clinton disagrees with me on some of this...." and turned the microphone over to her to let her lay out her plans.
