"Hi. This is Bill Scher from LiberalOasis.com How do national political polls and surveys work? Well every polling outfit is a private company that has different methodologies for their polls. So no one poll is the same as one another and it makes it very difficult to compare different polling results. Wordings of the questions is different. The samples is different. How they weight their results is different. In fact, many people do not know this but almost every polling outfit will after they get a sample of respondents, they will then determine if the demographic makeup of that sample reflects the state, the city, or the country as a whole and if it doesn't then in almost all cases it does not, they will adjust the samples to reflect certain demographic criteria of the area poll. Since every pollster handles that differently, uses different criteria to weigh, it makes it really impossible to properly compare one poll to another and it's why everyone should always be skeptical of polling results because it is far more an art than a science."
