This may straddle the line between politics and history at this point, but if we didn't have the 22nd Amendment, which limits Presidents to two terms, could Bill Clinton have won a third term?
Specifically, I'm looking for polls, articles, or other data which shows that people at the time would have been willing to elect him a third time if they could. In the absence of a term limit, he obviously could have won a third time, but if the political climate was against him, then he likely wouldn't have. Likewise, looking back from 15 years later it's easy for people to say they would have preferred him to Bush, but that doesn't mean they would have made that choice at the time.
