H.W. Bush was good, Reagan was more mixed but I don’t think he was bad–just mixed results, Nixon was good in a ton of really important ways but also ethically corrupt beyond belief. W. Bush was misguided and largely a failure. I’m a Republican by the way, so I obviously have a different baseline than Democratic voters. But I think guys like Reagan and H.W. Bush while not perfect, had a pretty balanced approach to government. Reagan’s flaw was he bought too much in to voodoo economics (a term actually coined by H.W. in a primary debate against Reagan in the 1980 primaries), I was and am broadly in favor with not having marginal rates as high as they were pre-Reagan, but he cut income taxes too much. But he also was willing to raise taxes at times when it was necessary, helped strengthen social security. He also ignored the AIDs crisis, the whole Iran-Contra thing, so that’s why I view Reagan as a mixed bag.
I think H.W. Bush was a pretty good President, moderate, good manager, fiscally responsible, no major scandals, utilized the U.N. for exactly what it was intended when Hussein invaded Kuwait–to prevent and deter wars of aggression. He built a coalition fully backed by the international community and pushed the Iraqis out of Kuwait. He was just unfortunate to be up for reelection at a time of economic malaise, and he campaigned weakly in 1992 against a very likable and energetic Bill Clinton.
