Doh!
I was about to fall asleep last night and had a revelation. I figured out what the problem is, and CNBC has been vindicated for cooking the books. The poll originally mentioned here and the one from last week are two different polls. The one we were voting on last week said:
"Should all online gambling be legalized in the United States?"
while the one that Ace in the Hole posted the link to said:
"Should wagering on sporting events be legal in 50 states?"
Here's the link to the poll we were voting on last week, with the final results 91/9 YES.

In other words, this presumably un-manipulated poll further vindicates our position.
