Maybe something like this?
Stein/Honkala 322 EV Goode/Clymer 128 EVJohnson/Gray 88 EVThe Libertarian and the Constitutionalist split the right-of-center vote, with the Libertarian doing better out West and the Constitutionalist doing better in the South and Great Plains. I gave the libertarian Indiana and Georgia, since they tend to vote pretty strongly for Libertarians compared to the national average. Also, just for the record, I think the Constitution Party wouldn't mount much of a campaign if the other two parties were the Libertarians and the Greens, and would still be a third party. This map is meant to represent what a close three-way race would look.
