It’s not a ‘meaningless’ statement.
It’s still 3 points higher for Trump in that poll since July which was released only 4 days ago on the 24th September, and that it is a post debate poll. 3 points is still a trend.
We see Trump in New Hampshire that he is still in double figures over the fading iCarly, and 3.5 times higher than Carson.
And this New Hampshire state polled 114 voters over that dumb national WSJ/LSDNBC poll.
What’s does that dumb WSJ/NBC poll average per state Con?
Yes, only 4.6 voters per state. Idiotic. The New Hampshire state poll is 72 times higher over the NBC poll average per state.
My point is that because they polled only in July and then last week, the difference between the two polls doesn't tell you anything about the trend now. Yes, he is up 3 points over where he was in July, but there is no way to tell what has happened in between. Maybe he was up 10 points in August, then lost 7 points of that gain. Maybe he was flat until last week, then spiked up 3 points last week. The point is, with no comparable polls between July and last week, it's hard to tell what the current trend is.
That is one of the reasons that early polling--especially early state-by-state polling--does not tell you all that much. Much of the value of polling comes in the aggregation of polls, to tell trends, etc., and early polling (and, again, especially early state polling) is relatively sparse.
