Electoral college probablities

In the US presidential election, the winner is determined
by electoral vote rather than by popular vote.
What is the chance that the two will give different outcomes
in an otherwise close race?

Make simplifying assumptions, such as an odd number
of equi-populous states.
In a two-candidate race, voters everywhere vote randomly
for one of the two candidates.
Every state has the same (odd) number of voters,
and the same number of electors --
the winning candidate within each state gets all of that state's electors.
What is the probability that the candidate winning
a majority of the overall vote will lose in a majority of the states?
