Abortions aren't the only places to get embryonic stem cells. Many of these cells are readily available in the umbilical cord at birth. The baby certainly does not need them, and otherwise the cord will just get thrown away. There are exactly how many live births at hospitals in this country alone every day?
The argument against stem cell research is flawed. It's flawed in the fact that embryonic stem cells don't always have to be harvested from aborted fetus tissue.

First two were just as much due to your party. Third one... well that's your opinion, and we prefer to keep religion out of it.

I very much agree with the President's decision on this matter. It has been too long that we have neglected to allow the studying of stem cells to their full extent.
These cells have the possibility of providing us with many cures and or treatments for a variety of diseases that affect millions of people all over the world.
It may upset some people because of their nature, but we need to look to the future on this subject and cannot stop funding of vital projects because of outdated ideology.
Stanford Researchers Announce Immune Problems With Embryonic Stem Cells
Scientific American, August 22, 2008
Following experiments with mice, Stanford University scientists have announced that stem cell therapies which use human embryonic stem cells (hESCs) have a high probability of failing because of immune rejection. In these studies, mice that were injected with hESCs exhibited an immune response which is at least as severe as that triggered by organ transplantation. Consequently, all the transplanted stem cells were killed by the immune system within a week. The Stanford researchers used molecular imaging technology to monitor the hESCs after injection, which revealed that the hESCs began dying within a week of injection and were completely dead by 10 days. When more hESCs were subsequently injected, they were found to die much more quickly, within 2 to 4 days, due to the already fully activated level of the immune system defense response. Even when the animals were given tacrolimus and sirolimus, two mediations that are commonly used to suppress an immune response, the hESCs lasted 28 days before dying but were still rejected and killed by the immune system.
Additionally, in all cases, the overall health of the animals continued to deteriorate, and the researchers were not able to determine any benefit from an increase in time before all the hESCs were eventually destroyed.
The U.S. FDA (Food and Drug Administration) has not approved the use of hESCs as a medical therapy, primarily because of the danger of teratomas, which are a well established risk of hESCs. A teratoma is a specific type of tumor which contains cells from all 3 germ layers of the body, which have often differentiated into specialized tissue such as teeth, hair and organs, and which therefore make these tumors particularly hideous and dangerous. The ability of embryonic stem cells to form teratomas is, in fact, the defining trait of embryonic stem cells, and the ability of a cell to form a teratoma remains the universal laboratory test by which embryonic stem cells are identified: namely,if an unknown cell is found to form a teratoma in the laboratory, then it's an embryonic stem cell, whereas if it doesn't form a teratoma, then it's not an embryonic stem cell. Teratoma formation, however, is certainly not the only risk posed by embryonic stem cells, and once again we are now reminded of the dangers of immune rejection that are inherent in embryonic stem cells. Adult stem cells, by sharp contrast, do not pose any risk of teratoma formation, and some types of adult stem cells, such as mesenchymal stem cells (MSCs), are known to be "immune privileged", meaning that they do not trigger an immune response.
According to Dr. Joseph Wu, a Stanford radiologist who led the recent research, these findings, which reveal such a strong immune rejection of embryonic stem cells, constitute "a reality check".
On Wednesday, only two days after he lifted President Bush’s executive order banning federal funding of stem cell research that requires the destruction of human embryos, President Barack Obama signed a law that explicilty bans federal funding of any "research in which a human embryo or embryos are destroyed, discarded, or knowingly subjected to risk of injury or death."
The provision was buried in the 465-page omnibus appropriations bill that Obama signed Wednesday. Known as the Dickey-Wicker amendment, it has been included in the annual appropriations bill for the Department of Health and Human Services every fiscal year since 1996.
The amendment says, in part: "None of the funds made available in this Act may be used for—(1) the creation of a human embryo or embryos for research purposes; or (2) research in which a human embryo or embryos are destroyed, discarded, or knowingly subjected to risk of injury or death."
Found in Section 509 of Title V of the omnibus bill (at page 280 of the 465-page document), the federal funding ban not only prohibits the government from providing tax dollars to support research that kills or risks injury to a human embryo, it also mandates that the government use an all-inclusive definition of “human embryo” that encompasses any nascent human life from the moment that life comes into being, even if created in a laboratory through cloning, in vitro fertilization or any other means.
“For the purposes of this section,” says the law, “the term ‘human embryo or embryos’ includes any organism … that is derived by fertilization, parthenogenesis, cloning, or any other means from one or more human gametes or human diploid cells.” (The entire verbatim text of Section 509 of the omnibus spending law is reprinted at the bottom of this article.)
At a widely publicized White House ceremony on Monday, President Obama signed his own executive order lifting an executive order that President Bush had signed in 2001. While allowing federal funding of research involving embryonic stem cell lines that had already been created from embryos that had already been destroyed, Bush's 2001 order denied federal funding to research that required the killing of any additional embryos.
