Said question to label me either ignorant, a traitor, or a Bush fanatic..

What was the pro-life legislation that Reagan introduced?
Answer: none, since presidents generally don't introduce legislation and, at the time, the Democrat-controlled Congress would have killed any attempt to pass such legislation. Reagan did institute the "Mexico City Policy" that banned federal money from groups that sponsored abortion in any part of the world (i.e. Planned Parenthood International). This is a policy since renewed by both Bushie I and Bushie II but Reagan did it first. Dutch nominated Antonin Scalia to the Supreme Court (we won't mention O'Connor and Kennedy). He wrote a book about his position on the issue and made no secret of his support for the pro-life plank in the Republican Party Platform.
I personally wasn't disappointed in Bushie II's position on stem cell research. It was better than I expected from him since he's always been rather mildly pro-life. If I was to criticize Dubya, it would be in other policy areas.
