Everyone invited to speak at the convention has their speeches vetted by the Romney campaign, though it's of course possible for someone to go off-script.
Btw, back in 1998, there was a similar "rapes don't result in pregnancies" controversy in Arkansas, and Huckabee defended the guy (Fay Boozman, brother of the current US Senator), and gave him a job. Not just gave the guy a job, but put him in charge of the state's Department of Health(!):
linkCan you imagine what would be happening now if Huckabee had run this year, and gotten the GOP nomination? The Akin thing would stick to Huck without much difficulty, because of his past actions with Boozman.
In any case, this combined with the Clemmons pardon should end any talk of Huckabee having a chance at winning the GOP presidential nomination in 2016 or beyond.
