The thing is, even Trump +5 isn't crazy given NV will be close. Outliers like that will happen. but Trump +12-14 is just on another planet.
Trump +5 is not an outlier. Trump +12/14 is one, but MC had Trump +11 a few weeks ago. Polling average w/ NYT poll is now Trump +7. A Biden +1 internal is about as much of an outlier as the NYT poll, even if the Biden +1 is magnitudes likelier to be the final outcome.
Polling is a snapshot, and the current state of the race in Nevada is a Trump blowout. Ralston probably sees more NV internals than anyone and he has echoed the Trump +5-7 public state of the race.
