They haven't nominated anyone. That happens at the convention which is more than a year away.
Furthermore, I wasn't aware the Republican party dumped the pro-life plank from it's platform. There's no evidence to even back that up. None of these candidates are the party, they are members of the party.
I found out from a friend who listens to the Bill Bennett show early in the morning that Rudy has appointed a bunch of liberal judges in New York; the opposite of what he is saying he will do as president. If people can't count on Rudy appointing conservative judges than his support for legal abortions becomes a whole lot worse.
