The polls are looking pretty accurate in NY-03
After that first dump of votes from Nassau County about half an hour ago it looked like Suozzi could have pulled off a double-digit win over Pilip. But with more votes coming now, it looks like those were Democratic-friendly early votes, meaning the Democrat's margin will end up in the mid-to-high single digits.
That is higher than, but really not so not so different from, the polls. The four polls we got of the race with the final set of candidates had Suozzi up by an average of 3 points. So if he wins by 6-10 points, we'll have a 3-7 point polling error in terms of the margin between the candidates.
That's a lot less than the average error for a House general election poll, not to mention polls of House special elections (which tend to be even less accurate). So, maybe this a good reminder for everyone: trust the polls, not the vibes (within reason).
