Now we move on to methodology.
Methodology includes some of the aspects above, but also includes such things as where the call lists for the polls came from, how they are administered, and how clear the questions are.
A truly neutral poll will be written with clarity and obvious delineation between choices. How many of them are?
Polling organizations get their lists of respondents in a number of ways, but most come from your voter registration, IIRC. They will only use the information provided, and can only work within that dataset.
They also depend on a person's willingness to participate. If you work two jobs, or have kids, or are caring for an ailing relative, or are in school, how much of your precious and limited time
Consider, then, the people who *can* spare the time: people with 9-5 jobs. The retired. The sample is going to skew older and wealthier for just these reasons.
When you consider all of this, it's hard to imagine how you can get a representative sample, even with a very well-curated phone list.
