Untill we see the "guts" it is hard to make a hard call on what the poll actually said.
Finally, even the very best can't get around statistical errors. Assuming a 600 sample size, 1 poll in 20 will report a lead that is wrong by 8%.
Agreed.
And, yes, the sample was about 600 (625 likely voters, to be exact).
I'm not sure when or if we'll see the "guts", since I don't know how this came out. But I hope we do see them. I don't want to overanalyze or overemphasize one measly poll, but I certainly found its results intriguing.
