I didn't know whether to put this poll in its own thread or in this one, but the Cleveland Plain Dealer and Baldwin Wallace did two polls of Cuyahoga County.
Baldwin Wallace found a 54.0% to 21.3% lead for Clinton with just over 10% going to the third parties and another 14% undecided. The Plain Dealer did a poll which pushed the undecideds hard and found Clinton leading 65-26. The first scenario leads to a Clinton loss in OH; the second scenario is a Clinton win in OH with Obama 2012 turnout. They also note that Trump is lagging all previous Republican nominees in Cleveland by raw percentages
