We have now obviously reached that point in the campaign where the polls start to contradict each other, for whatever reason.
"Because this is registered voters" is a good place to start.
The idea that a race in New York could be close at this point, given the candidates, is a factor of the national mood/enthusiasm gap and nothing more. A registered voters poll won't show an enthusiasm gap at all.
Not that I'm saying Cuomo/Gillibrand will lose or anything, it's just that a poll of registered voters would
completely and totally miss that boat.
