Getting ahead of a potential polling debate
Polling a special election is already tough. Add in a snowstorm, and it's even tougher.
Turnout in a regular general election — where comparable data comes out in every congressional election, every two years — is much easier to gauge than turnout in a special election. We just don't have comparable data for how voters behave when a vacancy is being filled in February of a presidential year. As Elliot pointed out before polls even closed, the few public polls of the race found Suozzi with a narrow lead, but one within those polls' margin of error.
The point is: If the polls are off tonight — and I'm not predicting that they will be — it doesn't mean they'll be off in November.
