No Polls?

I couldn't find any polls on Referendums C and D in this morning's Denver Post. You would think that 2 days before the election for arguably the most important ballot issue in the last 5 years, that there would be a poll. Nope. Not even a hint. Anybody know why? In this story, they say it's too close to call, but it would be nice to know the trends. You can find links to all of Colorado's TV stations here.
