Clinton still would have won the election without Perot, but it would have been closer. On a state by state basis, it looks like there are a handful of states that Bush most likely would have won without Perot on the ballot.
Maine
New Hampshire
Georgia
Montana
Colorado
The states that cost Bush in 1992 probably went for Dole in 2000.
Montana, Georgia, and Colorado are in this category as was Nevada back then. I would argue that Tennessee was in that category as well; it would have went for Gore in 2000 if it were not.
