To soon to tell. Only 366 people answered that poll.
The margin of error is 6 points. The only thing a bigger N will do is reduce that MoE.
You can see where it is settling.
Now of course this is only one poll, it could be an outlier. Also, since the poll isn't of a randomly selected population possibly the weights the pollsters used to accommodate for that aren't strong enough.
But +17, is a very large result.
