Having done polls, I can tell you right now that reeks of a poll looking for a pre-desired result. Doing polls was my first job out of high school. They drilled it into us that our #1 job was to never, ever bias the poll or the respondents.
We polled the 96 Presidential election, and I still remember the first 5 questions.
-Is anyone in the house over 18? (If no, call was ended, but I don't think we ever got that other than parents not being home @ the time.)
-May we speak the the member of the household who is over 18 and had the most recent birthday? (Not the youngest, but the last birthday. This was to try and randomize who we spoke to and avoid getting too many women since they are more likely to answer the phone.)
-Are you registered to vote? (If they said no, that was the end of the call.)
-Do you plan to vote in the upcoming election? (If they said no, we'd prompt them with "are you sure" and if they said no again, that was the end of the call.)
-Do you plan to vote for Bill Clinton, Bob Dole, or Ross Perot?
Afterwards we asked some other questions about why they were going to vote for their candidate of choice and then demographic questions, age, race, gender, income level, party affiliation etc.
IIRC, we had Clinton winning with 56% of the vote, and he didn't even get 50%. And this poll was done with the intention of not being biased. I have never, ever trusted polls since having that job since I know how they work and know how easy it is to bias the results.
