The 490,000 that failed to register, will probably vote though, whether they show up for it or not. This will probably be the most fraudulent election in history.
I have a list of the Cuyahoga County voter rolls on disc. You would be SHOCKED at the number of 120 year old active voters my county has in it, or used to have in it as recently as 2010. There where over 1.5 million registered to vote in Cuyahoga(Cleveland) County in 2010. Yet, there are only 1.3 million people in the county, including children and non-citizens. Now there are close to a Quarter million FEWER registered voters (215,000) in Cuyahoga County. MOST of those where active Democrat voters in 2008.
I assure you the Democrats are very nervous that they do not have the requisite dead voters to carry the day.
It has always been said that if the Democrat nominee doesn't come out of Cuyahoga County with AT LEAST a 100,000 + vote margin, THEY CAN NOT WIN OHIO. Outside of Cuyahoga County and Franklin County, the State of Ohio is very Republican heavy.
