Being a Catholic myself, I agree.. wondering if it comes down to Hillary or Rudy will they suggest we go third party or stay home... ;)
Many Roman Catholics I know, who have voted Republican, will choose Hillary. The anti-abortion plank is all that holds them in the Republiucan party. They are anti-death penalty, pro-universal healthcare and for welfare, seeing those as social justice issues. Abortion was the deciding issue and if abortion is out of the debate, they go back to the Dems.
I think the point is to keep it from becoming a choice between Hillary and Rudy. He has not been annointed, to my knowledge, and I think it's a mistake to assume that he MUST be the candidate. Aside from that, the general Catholic position at the moment is to vote for the one that you think will do the least harm.

10. What if all the candidates from whom I have to choose are pro-abortion? Do I have to abstain from voting at all? What do I do?
Obviously, one of these candidates is going to win the election. Thus, in this dilemma, you should do your best to judge which candidate would do the least moral harm...

However, the website I cited also provides the following guidance, which is relevant for the GOP primaries:

4. If I have strong feelings or opinions in favor of a particular candidate, even if he is pro-abortion, why may I not vote for him?
As explained in question 1 above, neither your feelings nor your opinions are identical with your conscience. Neither your feelings nor your opinions can take the place of your conscience. Your feelings and opinions should be governed by your conscience. If the candidate about whom you have strong feelings or opinions is pro-abortion, then your feelings and opinions need to be corrected by your correctly informed conscience, which would tell you that it is wrong for you to allow your feelings and opinions to give lesser weight to the fact that the candidate supports a moral evil.
3. If I think that a pro-abortion candidate will, on balance, do much more for the culture of life than a pro-life candidate, why may I not vote for the pro-abortion candidate?
If a political candidate supported abortion, or any other moral evil, such as assisted suicide and euthanasia, for that matter, it would not be morally permissible for you to vote for that person. This is because, in voting for such a person, you would become an accomplice in the moral evil at issue. For this reason, moral evils such as abortion, euthanasia and assisted suicide are examples of a “disqualifying issue.” A disqualifying issue is one which is of such gravity and importance that it allows for no political maneuvering. It is an issue that strikes at the heart of the human person and is non-negotiable. A disqualifying issue is one of such enormity that by itself renders a candidate for office unacceptable regardless of his position on other matters. You must sacrifice your feelings on other issues because you know that you cannot participate in any way in an approval of a violent and evil violation of basic human rights. A candidate for office who supports abortion rights or any other moral evil has disqualified himself as a person that you can vote for. You do not have to vote for a person because he is pro-life. But you may not vote for any candidate who supports abortion rights...
