Hillary and The Shrub: The popularity conundrum

If you think, as do I, that Bush is both the worst and most dangerous President we have ever had, you must also wonder, as do I, where his continued support (around 39% of the population, including a majority* of Republicans) comes from. Why do these people still support him?

Then there is the case of Hillary. The blogosphere and the TV punditocracy are drowning in negative statements about Hillary. Yet she retains a lead in most polls, both in terms of the primary and general election. Although I suspect that support is inflated, it does not seem to have occurred to anybody, at least anybody with a pulpit, to ask why people support her.

*I believe (based on a memory of a poll I read/saw) that a majority of Republicans still support Bush, but I have just spent a fruitless hour with multiple search engines and polling sites trying to find a recent poll that breaks down support by party. I wish this were the first time I've wasted an hour chasing down information that one would think would be simple to find only to come up empty. As far as I am concerned, search engines today (even Google - which I use regularly) still leave a lot to be desired.
