Assuming Bush drops out during the race...
Although some Bush voters go to Clinton, most go to Perot. Clinton is pretty much toast.
Ross Perot/James Stockdale: 55.87%, 323 EVBill Clinton/Al Gore: 43.79%, 215 EVOther: .34%
(Basically any state Clinton got 45% or more in, plus some others, stay, while the rest go Perot)
Perot still forms the Reform Party, who takes a sizable chunk of the House and Senate. In Perot's second term, he is able to end the Electoral College, move Election days to the first Saturday in November, and get a nationalized health care system. James Stockdale is elected President in 2000, although he isn't as popular as Perot was.
