She has no chance of losing Virginia. It's basically a blue state at this point.
I hear this a lot but I haven't seen much evidence that Hillary is leading in Virginia by a statistically significant margin that's greater than her national lead. Virginia and her national lead are both about +7. I'd be very surprised if Virginia was more than 3 points Democratic than the national average this election.
Regardless, I'd prioritize resources for Virginia and Colorado as first-tier states. If she holds the Kerry states (and solid blue New Mexico) plus Virginia and Colorado then that's victory.
