It was a poll for LCV though, so I take it with a grain of salt.
Poll by Glen Bolger (R) finds the race tied.

I wouldn't normally bring this up apart from the fact that Ralstron (arguably knows Nevada better than anyone else) thinks they are reliable and the fact that their poll was only of only few that showed Reid ahead of Angle by 5 which was the final margin of victory too.
If I had to guess, Presidential Race is between those two, so O+4ish for NV and Senate race is tied.
