The Post-ABC poll finds that 78 percent oppose cutting spending on Medicare as a way to chip away at the debt. On Medicaid — the government insurance program for the poor — 69 percent disapprove of cuts.

There is also broad opposition to cuts in military spending to reduce the debt, but at somewhat lower levels (56 percent)…

There is broad support for keeping Medicare structured the way it has been since it was instituted in 1965: as a defined-benefit health insurance program. Just 34 percent of Americans say Medicare should be changed along the lines outlined in the Ryan budget proposal, shifting it away from a defined-benefit plan. Under that proposal, recipients would select from a group of insurance plans providing guaranteed coverage, and the government would provide a payment to the insurer, subsidizing the cost. Advocates say this approach is more sophisticated than a pure voucher plan.
