Change isn't the greatest pollster (putting it mildly) but would this result really surprise you guys that much? Remember that Brown beat trash-tier candidate Josh Mandel by only 6 points in 2012, and Ohio has veered sharply to the right since then. Yeah, 2018 will likely be a better environment for Dems, but 2012 wasn't exactly a poor environment for Senate Democrats either. I've always thought this race was going to narrow. I'd be way more shocked at Brown winning by double digits than I would be at him winning by 4.
Right now it's an outlier. Every other poll has had Brown double digits
