Maybe you should have read the WHOLE article yourself:

When we asked Planned Parenthood whether insurance companies were denying coverage for contraceptives, the group pointed us to the text of a 2003 amendment introduced by Sen. Patty Murray (D-Wash.), which would have prevented insurance companies from denying such coverage. The text of the amendment includes the claim that "half of traditional indemnity plans and preferred provider organizations, 20 percent of point-of-service networks, and 7 percent of health maintenance organizations cover no contraceptive methods other than sterilization." This could be referring to a 1993 Guttmacher study showing that 49 percent of indemnity plans did not cover contraceptives, and that less than 20 percent of large-group indemnity plans and PPOs and less than 40 percent of point-of-service plans and HMOs covered the full range of reversible contraception options. By the time the Murray amendment was written, that information was 10 years out of date. Now, it's 15 years old and irrelevant, given Guttmacher's more recent findings.

Incidentally, McCain voted against the Murray amendment. In 2005 he voted against a similar amendment, this one proposed by Hillary Clinton. Whether or not he lacks an informed view, as he said, he has in the past opposed legislation to enact a federal mandate for contraceptive coverage.

To be sure, McCain can thank his own campaign for inspiring the ill-informed question that left him so exposed. On July 7, McCain campaign surrogate Carly Fiorina said at a press event: "There are many health insurance plans that will cover Viagra but won’t cover birth-control medication. Those women would like a choice."
