The Declaration of Independence states that all men are endowed by their Creator with the right to life, and the fourteenth amendment to the Constitution guarantees equal protection under the law; there's a real argument to be made that murder laws that don't protect unborn children run afoul of that clause.

That argument really helped our cause in 1973, right?

Does that decision make the argument any less true?

That was 36 years ago. Amazing medical advances have been made in those 36 years.
In 1973 there was no such thing as ultra sound or sonograms. IIRC, even the doctor could not hear the baby's heart beat until 3-4 months. Medical advancement has completely changed the argument, but in this case, many don't want to look at the "science" involved.

The Life at Conception Act, if passed, would define life as beginning at conception.
If that happened, the Preamble, 5th, and the 14th amendments would apply to protecting the lives of the unborn.
An admission made by the court in their Roe v. Wade ruling when Justice Blackmun wrote;
If this suggestion of personhood is established, the appellant’s case, of course, collapses, for the fetus’ right to life would then be guaranteed specifically by the Amendment.
