Why were Nevada polls so off the mark in 2010?

On wikipedia, it lists a bunch of polls leading up to the 2010 race, and Reid was consistently losing by 3-4 points. Even in late october. Were there polls out there that were showing a different picture, and Wikipedia just didn't include them, or was this a shocker?

Hispanics and Democrats in general were understimated as was the the GOTV on the part of Reid's machine. Angle struggled with the traditional swing voters, the ones that might have actually voted for a Heck or Heller against Reid, and thus when the electorate turned out to be less Republican, Reid won reelection. The same thing happened in Colorado where Democratic turnout killed Buck, but only because Buck had already lost the soccer Moms in Jefferson and Arapahoe county.
