I didn't notice anyone saying anything favourable about Clinton. If someone pointed out that smoking is bad for the health what relevance would it be, for example, to point out that eating junk food is bad for you too?

Bush and Clinton have both been very bad for the political health of the country that was entrusted to them (though "entrusted" is perhaps not the word for for what happened in November and December 2000. That'd be a bit like saying you were "entrusted" with someone's watch because you stole it off them.)
