We need to be smart about surveys. I've heard people who work in marketing say they don't believe in surveys because in all their life they've never been part of a survey's random sample. This is basic innumeracy (how many possible sets of 1,800 respondents are there in a population of 110 million?) compounded by demographic ignorance (a marketing executive likely belongs to a sliver of the AB "class," a random sample of which must be proportional to the actual size of that demographic class).
To be clear: Surveys are not determinative—at least until the second survey round of the 90-day campaign period. That means that it will be the survey cycle about four or five weeks into the national campaign period where we may find public opinion consolidating.
