B- pollster with a D+0.1 bias according to 538.
Given the media boner for Bayh so far
(and I'd say rightfully so?) and the resulting polls, I'd say at best this is still a toss-up but it seems more likely now that Young ekes out a small win.
Also, maybe worth noting but this pollster had Bayh only +1 in early October while others subsequently had him up by +6. But, then again, Monmouth was one of those +6's and they had it tied last week, soooo..!
