Q. What was the last major health entitlement to be enacted in the U.S.?

A. Medicare Part D, in 2005 by a Republican Congress and Republican President.

What's more, the original fears about the explosive costs of the Medicare Part D prescription drug benefit have turned out to be unfounded. In fact, as this recent article notes, the ten-year cost for the benefit is now expected to be 40% less than the original CBO estimate. And this "government-run" program is working very well, and is extremely popular with those taking advantage of it.

Granted, Republicans would undoubtedly say that Part D is only working well and costing less because they created it, not Dems, but I still think it might be worth reminding them of a few of these inconvenient facts.
