Wes Colley, who runs one of the college football BCS ranking models, also did an electoral model. His model is much simpler, essentially taking the median poll result in each state.
Their predictions were basically the same as Sliver's, missing only on Florida (they manually broke a tie in the model on Virginia so count that however you'd like).
