The National Right to Life Committee is endorsing Fred Thompson for president. That’s a good group, but I remain confused. He opposes a constitutional amendment barring abortion and he has even done consulting, earlier in his career, for a pro-abortion organization. His Senate record was pro-life, though, but it seems to me that his pro-life credentials are no better than anyone else’s in the race. Why endorse anyone under those circumstances? Why not hold everyone’s feet to the fire, then back someone when the field has narrowed?
