Huckabee is the only mainline candidate I would even consider voting for, but I do find some things troubling:
His recent statements about abortion have been good, saying that no state should be allowed to legalize abortion any more than they should be allowed to legalize slavery. But he has said in the past that the states should be allowed to decide. And he currently claims that his position has not changed.
I think it's important to look at what he actually said. In an interview back in 2006 when asked he felt Roe v. Wade should be repealed he answered:
It would please me because I think Roe v. Wade is based on a real stretch of Constitutional application -- that somehow there is a greater privacy issue in the abortion concern -- than there is a human life issue -- and that the federal government should be making that decision as opposed to states making that decision.
So, I've never felt that it was a legitimate manner in which to address this and, first of all, it should be left to the states, the 10th Amendment, but secondly, to somehow believe that the taking of an innocent, unborn human life is about privacy and not about that unborn life is ludicrous.
This is a completely accurate statement of what should occur under the law
as it currently exists.
It's entirely possible to support the reversal of Roe v. Wade and returning the authority to ban abortion to the states in the short term, while support the passage of Human Life amendment to completely ban in nationally in the long term.
Now going back further (over a decade to 1995), I have seen it alleged that he supported a removing the call for a Human Life amendment from the Republican platform and replacing with just a call to turn the issue back over the states. However, the only source I've seen for that was a single sentence quote from a Press Release issued by the Fred Thompson campaign, which without having access to the statement in context I'm a bit wary of.
However, it's entirely possible he's weasel-wording a bit and when he says that he's "never changed positions" he means that he's always been Pro-Life as opposed to having always been for a Human Life amendment. But again, it's entirely possible even from that 1995 quote that what he's saying is to concentrate on reversing Roe v. Wade as matter of political strategy as opposed to opposing the passage of a Human Life amendment.
Everything he said made sense and was correct, until the end where he said that people have the right to do embryonic stem cell research if they use private funds. He'd just got done explaining that embryonic stem cell research destroys human lives, then says that people have a right to do it?
While I don't agree with him here, what he is talking about is research done on already existing lines of stem cells, not the destruction of of additional embryo's in order to create stem cells. I personally oppose even that, but this still puts him well to the right of McCain (who supports federal funding for stem cell research) and even the recently withdrawn Romney (who supported allowing private groups to continue to destroy embryo's to create stem cells).
