What was the last "Republican" Policy or Idea that was enacted and was actually a good idea?

15. Well, there were of course things Nixon did

that people have pointed out here, even if it were mostly due to a Democratic congress and a sweeping progressive mindset during that time period (IE: EPA, a better health care proposal, support of Keynesian economics, etc).

Though Nixon did seem to support a surprising number of progressive legislation, despite his self-professed hatred of liberals, I would say Eisenhower was the last truly respectable Republican President.

Otherwise, I cannot think of much good (if anything), that a Republican has supported in recent history. I must admit George Bush's immigration reform seemed rather promising (at least in my opinion). No matter what his motivation for it might have been, it could have been the one good thing he'd ever done during his administration. Yet, even he lacked the conviction to truly push for it.
