It is fun and interesting to fantasize about independents actually winning electoral votes. In reality, it is very, very unlikely to happen, virtually no chance.
The last independent or third party candidate to win any electoral votes was George Wallace in 1968. Wallace was an established conservative entity on the political scene in 1968 and had a solid base of support in the deep south, and was able to win 46 electoral votes and five states.
Perot, even with a better campaign would not have won any electoral votes. In 1992, it simply was not a realistic expectation.
Cuomo wins this election, but not without a fight. Much of the country would simply be suspicious of a northeastern liberal like Cuomo, however, Quayle would not be a strong enough nominee to win the Presidency, and there are too many doubts about Quayle's capacity for the job. Cuomo in 1992 would have lost to a more credible Republican nominee like GHW Bush.
Nunn, although a good VP pick does not help deliver any southern states, including his home state of Georgia, to the northeast liberal Cuomo.
All three VP nominees are good picks, however, when it comes right down to it, it would be the Presidential nominees that people would be casting their votes for or against.
Cuomo/Nunn 276
Quayle/Baker 262
