Aren't these the precincts which manifested massive vote frauds?
IIRC, these are the precincts where some recorded no Romney votes. And others reported exactly (very suspicious) two votes for Romney.
The above link is to the official Cuyahoga county results for the 1077 precincts. There are some 20 or so precincts with no votes for Romney and many more with just a single digit number.
The presidential race is the second set of results listed...
