Yes!
Personhood is the key.
That is why Blackmun, in Roe, said the court would ignore the “well-known facts of fetal development” because otherwise,
UNBORN BABIES WOULD BE ENTITLED TO PERSONHOOD
under the Fourteenth Amendment.
Duncan Hunter has introduced legislation to recognize the personhood of unborn children.
Does anyone know what the other presidential candidates have done about it?
Well, since the USSC has already ruled that under the 4th Amendment (i.e. Justice Blackmun's argument accepted), I don't know what a mere act of Congress (which is unlikely to pass in any event: Democrats aren't stupid, you know) would do to change that. Of course it would improve the standing of Duke Cunningham's buddy, the Duck Hunter, with one issue pro-Lifers who might vote in GOP primaries (if they're not sitting the primaries out 'cause they're mad at the GOP for some other real or imagined "slight" by that time). Other than that, however, I'd have to say that the 4th Amendment (even as interpreted by pro-Abortion, politicized "Jurists") would trump Duck Hunter's political stunt.
Below in quotes are Duncan Hunter’s own words:
“Duncan Hunter: Yes. You know, I’m the author of the personhood-at-conception bill which right now has over 100 co-sponsors ...that would define personhood as moment of conception, so, it would allow us to have a reversal of the effects of Roe v. Wade without a constitutional amendment.”
