The moreover that this poll was released before Rick Breckenridge, the Libertarian candidate, endorsed Rosendale so if we combine his numbers to Rosendale's, Rosendale would be leading by 6 points with 52 % of the vote.
This could account for the change of events. Breckenridge supporters were coming home to Rosendale even before the endorsement. That's generally what happens with third parties. I predicted a +6 Tester win last week. If he loses, there's a good chance the national environment won't be favoring Dems either.
