Reagan was very unpopular during long stretches of his two terms. If I'm not mistaken, his approval rating was in the mid/low-30s in 1984... not long before he buried Mondale in the '84 election. Bush Sr enjoyed approval ratings in the 90s before losing to Bill Clinton, who spent much of his first term doing about as well as Reagan did in terms of approval. Time tends to mellow people's perceptions of the president, especially if things aren't going well. The fact that Dubya's numbers are still that low indicates that people still blame him at least in part for the country's ongoing problems, and I think that's pretty rare.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
