This is not a particularly complex point, but it is one toward which Palin seems deliberately obtuse. It came up at the Republican convention last summer, when the Palins issued a statement about their daughter’s pregnancy: “We’re proud of Bristol’s decision to have her baby.” Again, in the world according to Palin, there would be no decision at all. Abortion would be illegal except to save the life of the mother.

I respect Palin’s decision not to “make it all go away.” She describes her doubts about whether she had the fortitude and patience to cope with a child with Down syndrome, and, with the force of a mother’s fierce love, the special blessing that Trig has brought to her life. She speaks as someone who is confident that she made the correct choice.

For her. In fact, the overwhelming majority of couples choose to terminate pregnancies when prenatal testing shows severe abnormalities. In cases of Down syndrome, the abortion rate is as high as 90 percent.
