Politician Stances on Stem Cell Research

The current politicians' stances on Stem Cell Research (SCR) cannot be summed up easily.
I hope this helps anyone who is interested in knowing the current stances on SCR, and helps eligible voters make a choice come election time.

Hilary Clinton is strongly in favor of SCR, and promises to raise funds for future SCR and to expand it to include more stem cell lines.

Barack Obama also favors SCR, but not as strongly as Clinton. He believes that stem cells provide the key for future medical breakthroughs, but is leaning heavily towards only using existing stem cell lines.

John McCain is strongly against using human embryonic stem cells for research, but is more than willing to expand research using adult stem cells.
Here is his view on the subject:

Ron Paul has no problem with SCR, but is against the federal funding of it. That is why he has backed President Bush in his veto of the Stem Cell Research Enhancement Act of 2005.
