Point of information.
As far as I know, Ron Paul has only said that he supports unrestricted access to emergency contraception, not to Mifepristone (RU-486).
Mifepristone is not what’s usually referred to as “the morning-after pill.” “Morning-after pills” are emergency contraceptives such as Plan B or Preven, which use high doses of hormonal contraceptives to prevent ovulation or implantation if taken within 72 hours of unprotected sex. (You can get about the same effect by taking several doses of a regular oral contraceptive at once.) EC pills only prevent pregnancies from beginning; they cannot abort one once it has begun.
Mifepristone, on the other hand, is a chemical abortifacient that can be used to terminate a pregnancy during the first two months.
As an Ob/Gyn, Ron Paul would be acquainted with the differences, so I expect that he considers EC drugs to be morally no different from traditional oral contraceptives, which work the same way. (Some of the antis believe that hormonal contraceptives and EC are equivalent to abortifacients, at least for purposes of faith and morals, but lots don’t. I expect Paul is one of the latter.)
As for his current views, his website currently offers the following.
I take it that the presence on his campaign website indicates that this still reflects his beliefs.
… In Congress, I have authored legislation that seeks to define life as beginning at conception, HR 1094.
…As an OB/GYN doctor, I’ve delivered over 4,000 babies. That experience has made me an unshakable foe of abortion.
… Many talk about being pro-life. I have taken direct action to restore protection for the unborn.
One such action, which his issues page doesn’t mention, was to vote in favor of the recent federal procedure ban on so-called “partial-birth abortion.” An unfortunate lapse from his putatively federalist position.
Fun fact: my grandfather actually knew Ron Paul decades ago through the Association of American Physicians and Surgeons, and through politicking within the Texas Medical Association. Granddad had Paul over to his house for several conversations about libertarian ideas, and introduced him to the notion that the government medical licensing should be abolished, which Paul found to be quite shocking at first. He also tried to convince Paul that abortion should be decriminalized. Fortunately, in time, he managed to win Paul over to the former idea. Unfortunately, he failed to win him over to the latter.
