Other than George Bush in 2000, when was the last time a candidate successfully ran a campaign of entitlement?
The failures (both in primaries & generals) roll off the memory....Kerry, Dole, Mondale, Hart Humphrey (68 generals AND 72 nomination), etc.
I don't count Bush Sr's 1988 run as that was more a combination of image-buiding and negativity. Dole was more of the entitlement candidate that year, in the primaries.
It was probably Nixon in 1968. And that panned out real well.
