Texas Governor Rick Perry is calling Medicaid a "failure,'' as he defends his decision to oppose any expansion of the program as part of the national health-care overhaul.

Today, Perry told Fox News that adding uninsured Texans to Medicaid, as proposed by the overhaul recently upheld by the Supreme Court, "is not unlike adding a thousand people to the titanic.'' He says Texas won't participate in the expansion or create a health care exchange required by the law. He says he doesn't want to be part of ``socializing health care'' in the Lone Star state as part of a bill he considers unconstitutional. Perry announced his intentions to oppose a state insurance exchange and a Medicaid expansion in a letter Monday to U.S. Health and Human Services Secretary Kathleen Sebelius.
