If this holds, Udall is on pace for a 8-11 point victory.
Considering even Buck was coming within 5 points of Udall in some polling last winter, an 8-11 Udall victory is out of the question with Gardner being a much better candidate for Buck.
You're assuming that Latino turnout will be EVEN HIGHER than it was in 2012, and there's NEVER been a midterm election that had HIGHER turnout among minorities then the presidential election immediately preceding it. Midterm election turnout is always more republican than the presidential election immediately preceding it, even in years like 1998, so any suggestion that Udall can outperform Obama is ridiculous and has no validity whatsoever.
I think he was being sarcastic.
Gardner is not going lose, let alone by 8 to 11 points.
