Pollsters doesn't just interview the first 1000 people that the guy
with
the clipboard can detain. The sample they use will often have been
selected
from a larger sample based on models of the population demographic.

  Exactly.  How do they know how to model the population demographic?
Other surveys, samples, and wild-assed guesses.


Yes, and of course, census data.

  Even if they did interview the first 1000 people they met on the
street, that data would allow them to set bounds on population
behaviour, based on key assumptions and models.


Maybe so. Ask your nearest statistician how much money would they'd invest
in an enterprise that relied on market research done like that.
