Gotcha.  You're saying if it went Republican, it did so against the net effects of the Jews.  What I'm trying to tie in here is if enough Jews "defected" to make the difference e.g. if 80% of Jews going Dem became 60% because [Bush/W. Bush/etc...] had enough appeal.  I'm claiming Jews can influence a race not only by going solidly Dem, but also by deciding not to.  The article I cited states the amount of time candidates spend on Jews is precisely because they (~20% of them) are swayable.  That being the case, narrow Republican victories could also be a result of Jewish response to a candidate.

This being the case, 2000 Florida could be a result of Jewish voters if either: (1) enough Jews were attracted to W. Bush to throw the state, (2) the state actually went Democratic by voter intents (again this is possible but contentious, or (3) Jews made the race close enough to require Supreme Court intervention, which is itself a political outcome and has profoundly influenced the voting method there, as well as affected ideas about W. Bush.  If any one of these three is possible, we can't discount the effect of the Jewish vote in Florida 2000.
