NV-CNN/ORC: D: Clinton 48% Sanders 47%; R: Trump 45% Rubio 19% Cruz 17%

IIRC, the real Iowa result had Sanders make a net gain of four points compared to the final RCP average for the state, and Sanders overperformed his final RCP average in New Hampshire by nine net points. Hopefully this means that pollsters have a knack for overpolling Clinton supporters and underpolling Sanders supporters, which could actually translate to a slight lead for him in the real NV result (even if it's already ORC doing the polling).

For some reason, Nate Silver has decided to update his predictions to a 67% chance of a Clinton win and 33% chance of a Sanders win, which is pretty different than the 51% chance for Sanders/49% chance for Clinton prediction that he had earlier.
