Kentucky is richer than West Virginia
Kentucky is more educated than West Virginia
Kentucky is less white than West Virginia
Kentucky is younger than West Virginia

Granted, it's just a comparison -- on the whole, it's still good Clinton margins, but via which exact demographic measure is Kentucky more favorable to her than West Virginia was?

If I had to guess, 30 points seems like a reasonable spread, and it's more in line with the other pollsters:
Clinton +32 (SUSA 5/9-11)
Clinton +27 (R2k 5/7-9)
Clinton +25 (Ras 5/5, 13% undecided)

But, hey, my guess is based on the preponderance of all polling data and the actual demographics breakdown, rather than one ARG poll and wishful thinking.  I could be way off.
