Well, Speaker Gingrich and Senator Santorum certainly questioned them in this debate (full transcript at

GINGRICH: After he became pro-life, Romneycare does pay for tax-paid abortions. Romneycare has written into it Planned Parenthood, the largest abortion provider in the country, by name. Does not have any right to life group written into it.
He did appoint pro-abortion judges. And a branch of the government which included his appointees did agree to fund an abortion clinic for Planned Parenthood. All that occurred after he had become pro-life.
Now, those are all facts which we validated, and it seems to me that’s a legitimate part of the campaign, is to say, “OK, if you’re genuinely pro-life, how come these things are occurring?
SANTORUM: I just want to make one point. And a lot of legislatures here — legislators here in the room and they — and they know this to be the truth, that if you write a piece of legislation and you — and you say medical care and you do not specifically mention that abortion is not covered, we know from every court decision at the state and federal levels that the federal courts and state courts will require it.
That is someone (sic) every governor knows, every state legislator knows. And so when Governor Romney did not put that in the bill, you can’t say, “Oh, gee, surprise, the court made us cover abortions.” He knew very well that the court would make them cover abortions. That’s number one.
Number two…
(APPLAUSE)
Number — number two, what we’re talking about here is someone who’s not going to just check the boxes and say, “Yes, I’m pro-life.”
We’ve got a lot of folks who just whisper into the microphone that they’re pro-life, and then you have other people who go out and fight the battle and defend life and come out of the trenches and actually work to make sure that the dignity of every human life, innocent human life in this country is protected.
And I’ve done that.
