To obtain some answers, you should have posted your own map....
And you should have dropped VP picks, as it seems rather impossible to have Chuck Hagel running with Clinton and not very probable to have Romney running with Lindsey Graham.
I think Clinton/Strickland, Romney/KB Hutchinson and Obama/Biden are more realistic tickets.
Here's my prediction in this case:
317 - 142 - 79 : Romney is able to win the South-Western states and Wisconsin, and even to keep Virginia and NC and Florida (yes !), due to 3-way races that are very difficult to predict.
Minnesota, Missouri, Maine would also be very tight races.
