These are interesting polls that I found on Gallup polls. One measures by political party, the acceptance of embryonic stem cells which for each party was over 50%.  The other shows individuals personal point of views of stem cells. Again there is an overwhelming amount of support for stem cells. This shows that because of the great promise of stem cells the acceptance has improved.
