"None of us are for cloning..."

This is a quote from yesterday's Iowa townhall meeting by John Edwards in the context of answering a question about stem cell research.

In all probability, every other presidential candidate will take a similar stance in supporting the go'vt funding of embryonic stem  cell research,  so the distinquishing factor in my mind would be which candidate has the better understanding of the science of this and other medical or technological topics.

I would like to ask Edwards if he could explain the difference between reproductive cloning and somatic cell nuclear transfer (therapeutic cloning), or even what a stem cell is. It's important for the person running for the highest office in this country demonstrate the intellectual curiosity needed to grasp these subjects rather than deliver a scripted answer. His or her term will face question about other technological advances that will require more than a superficial understanding.
