With all due respect. KY is not needed for a Obama victory.
Look at Poblano's startling analysis of what Obama can achieve if new voter registrations of AA's increased by 40%.
He would win a baseline EV of 322 and his increase his popular vote margin by 3.4%.
Increase that level to the youth and latino vote and he will win a extra 40EVs.
Astounding.
