Interesting that their 'Undecideds' are flowing roughly half and half Yes and No, whereas the recent Resolve poll shows 1 Yes for every 2 No.
The Essential poll has been the consistent outlier. Someone recently posted a graphic here of all published polls, showing averaged trends. The JWS poll confirms those trends.
The 'Yes' side would now be having LOTS of discussion in their campaign bunker one would think.
