You can make polls like these say just about whatever you want depending on how you phrase the question. A couple extreme possible examples with online poker would be:
If you want the poll to say that online poker shouldn't be regulated...
Do you believe that online poker, known as the crack cocaine of gambling, should be reglated and therefore more accessible to millions of new Americans who could possibly start playing?
Or if you want to poll to say that online poker should be regulated...
In these though economic times do you believe that online poker should be regulated and taxed which could potentially bring in billions of dollars of tax revenue which could be used to help pay for such projects as new schools and highway repair?
I'm certainly not saying that fair and unbiased questions can't be asked. But who wants to spend the money to ask that type of question?
