A neat website that shows how the last few presidental elections would have ended up if the entire coutry used the Maine-Nebraska electoral vote method. Believe it or not, only one election of those shown would have gone the other way: the 1976 election would have gone to Ford. Maybe it is a good thing we don't use this method throughout the country.

Also, for your reference, from a Slate article just how Maine and Nebraska decide their electoral votes:

...Maine does not award all its electoral votes (there are four of them) to the presidential candidate who gets the most votes in the state. Instead, the candidate who wins the popular vote gets two electoral votes. The third electoral vote goes to the candidate who wins the popular vote in the 1st Congressional District and the fourth electoral vote to whoever wins the 2nd.
