This isn't something I'd ever thought I'd say but I think I'm going with the Quinnipiac poll.
Not commenting on the accuracy or results of either of the polls, but this is an
exact example of the "let's ride whatever affirms my beliefs and dog the opposing result as a pollster" nonsense that runs around here.
With respect, your preference or beliefs don't make a pollster, whether it be PPP or Bob Jones University polling team, accurate or not. With that being said, I don't think Sanders is leading in Ohio as of now. I'm just feeding food for thought.
