The reason the evangelicals did not fall behind Ron, who is Lutheran/Baptist instead of a Catholic is because he wouldn't agree to a Constitutional Amendment to prevent gay marriage. Is it your view that Rand would give them that? Because they were very specific in the pledges they wanted signed.
I have no idea what Rand would do regarding that. I'm saying that he needs those votes. Santorum won a lot of states. We won none. Santorums votes did not come entirely from people who required a pledge to sign an Amendment.
