Edwards or Graham, both who where on the final short list with Lieberman, both who I think would have given Gore Florida.
Graham was a former Governor and in the Senate from that state. But I dont suppose Gore realised when he made the decision in August 2000 what an error he was making or how critical Florida woyuld become on election day and beyond.
Florida is the only state where Gore outspent Bush. He spent something like 60 hours straight campaigning there before the election. And it paid off, more people clearly went to the polls intending to vote for him.
