Bush will sign a Partial Birth Abortion Ban. Bush will appoint a Pro-Lifer to the Supreme Court.
I think I see your problem now. You mistakenly believe that someone who's in favor of abortion in the cases of rape, incest or RU486, is "pro-life."
My definition of "pro-life" is someone who's against abortion. Period.
I tend to take people on their own terms. If they say they are pro-life, and do not stray too far from the ordinary meaning of the term, I consider them pro-life. While not conceding that Bush in fact holds the positions you imply, the absolutist position you hold is supported by 17% of the electorate. If you are not willing to work with those who are in agreement with you about other aspects of the issue, no restrictions will be made on abortion.
To the extent that you are able to accomplish this, you will be responsible for not saving the babies who could be saved, allowing them to die because we could not now save them all. This making the perfect the enemy of the good is a recipe for failure, and will allow the murder of millions who could be saved.
