Consistent trendline here; eventhough Its Zogby, Clinton does well in Va & OH better than CO, so the Dems are favored to win, making either state the bellweather, and making CO a not must win state. Different from what has been thought that SW is blue wall. Va or OH is the wall state.
Hillary has always had tons of support in the east and next to no support among whites out west. Nothing new there. Which probably makes it even more important for her to pick a running mate from a western state. She'll struggle with winning Colorado, perhaps even Nevada, if she goes for someone from Virginia or Ohio or something. Especially if she's up again Rubio or Bush.
