If you make the absolutely absurd assumption that
every OTL 1996 Perot vote would go to Dole (none to Clinton, none to Nader, none to Browne, none stay home) then Clinton would still win the popular vote in 1996, but would narrowly lose the Electoral College. (In addition to the 159 electoral votes he got in OTL, Dole would carry KY, NV, AZ, TN, FL, MO, OH, OR, PA and WI for an additional 133 electoral votes, giving him 292.

Actually, polls showed more Perot voters listing Clinton as their second choice than Dole.
