:::::::Hmm. Well then maybe decisive isn't a good word to describe the election victory. Had ~111,000 people (0.09% of those who voted) in three states voted the other way, Kerry would have won. Narrow seems to win out here as the superior descriptor. Really, it is neutral though, as just about every reputable source agrees that the victory was narrow. Decisive, on the other hand, is disputed by a large enough number of sources to prevent us claiming it as fact. Maybe we could put a footnote next to "narrowly" explaining that there is a clear consensus among reliable sources that the 2004 election victory was "narrow", although I really don't think it's needed.
