He is still one state short in the Silver model (or two small ones if they are NV and NH).
Not sure where that one extra state comes from. I’m hoping it is Colorado.
The way I figure it, he takes NC, FL, OH, IA, NV, and AZ. He needs to pick up one of the following to win:
NM, CO, MN, WI, MI, or PA. If he picks up MI or PA he doesn’t need NV.
