Carville is closer to the truth than you think.
The only reason we won is that manyDemocrats are clumped up in a few urban areas in few VERY Blue states.
If they spread out and change the demographics other states, (examples being Colorado, NC and Virginia...) they will be in charge.
Along the lines of your comment, why do you think Obama made his “Welcoming Communities” Orders, and seeded Muslim immigrant enclaves all over red states? These cuckoo birds will live off of the public, and breed busily. Long term demographic plan.
If urban voters move to fly over country they will discover their patriotic roots.
