I remember reading back in the 90's someone did two polls, both with the same questions but in different order. One started with negative things and asked what your opinion of Bill Clinton as president, Then went into positive things. The second one started with positive things, and asked your opinion of Bill Clinton as president, then asked about negative things. The one that started with positive things had a much higher opinion of Slick Willie. It won't have matter to me which order they gave me, I would have still said he was doing a piss poor job.
Also survey can be influenced by where they ask the questions. If they go to an area that is predominantly liberal Creepy Joe will be ahead. Also if they call me for a poll I usually don't answer if I do not know who is calling and if I do and it is a poll I have hung up on them.
