There's a year left to go and KS is a ruby-red state.
I would also say this, I don't expect this to last forever.
If we see Dems like Wendy Davis or this Davis start to take leads in ruby red states, small sign that GOP may lose the House because of GOP gerrymand in Romney districts. Kasich losing will probably signal that because the rigorous gerrymand.
It doubt that Democrats' statewide victory in Kansas (if that is the case) is much of an indication of anything nationwide.
Kansas has elected a number of Democrats for governor over the years.
