Not really. Cuban Americans fed up with the Clinton/Gore kidnapping of Elian Gonzales voted Republican in droves. Gore tried to fend this off by claiming he was against the kidnapping, but the voters didn't buy it. That was the largest block in play.
Also if you recall, one of the biggest issues in the 2000 election were voters, particularly on Florida's east coast, who voted for Buchanan. They alone generated the margin of victory in some areas where the Greens had little traction.
Nader/Green party voters wouldn't go for Gore (and they didn't) or any Republican candidate. No Green party voter is ever going to vote Republican - even for a RINO.
Trying to appease them is a waste of time. Losing core voters who can't afford to fill their gas tanks is how you lose elections.
And it wasn't just Florida. The democratic state of West Virginia voted for Bush. Without FL and WV, Bush would not have been elected.
WV felt double crossed by Clinton when he sided with the enviros on mountain top mining. Bush and Gore both campaigned on changing the definition of "waste" but WV didn't believe Gore because of Clinton.
