The problem here? The WBUR poll is pretty much the only poll that didn't show Trump taking a hit after the Billy Bush tape hit. That, to me, says it was probably an outlier. Yes, it could be the only one that's right, but that kind of thinking leads you into the Rasmussen-land described above.
Probably the best news for Trump comes from the NBC/WSJ poll that shows him
one point ahead in Ohio:
In Ohio, Trump holds a one-point advantage over Clinton among likely voters, 42 percent to 41 percent, with Johnson at 9 percent and Stein at 4 percent, although that margin is inside the poll’s margin of error.
That's nice, but it brings us to the real problem with all of these polls. Each of them were conducted somewhere between October 10 & 13. That means they all reflect "the tape" and his stronger debate showing, but contain little of the fallout from the groping accusations. It will take a few more days before the polls bake that into the data, so these numbers may be a bit pie-in-the sky.
The fact is, Trump is probably around 5-6 points behind Clinton. That's not an insurmountable figure, but you have to know that every time it looks like Trump is going to close the gap, team Hillary will scare up another accuser. If it looks like the Wikileaks releases are hurting her, one of her media allies will drop another "recently discovered" bit of footage.
At this point, it's a war of attrition. The problem is, it's tough to win that kind of fight when you're already behind the electoral 8-Ball.
